- Magnetic field strength is the intensity of a magnetic field at a given location. Historically, a distinction is made between magnetic field strength H, measured in ampere/meter, and magnetic flux density B, measured in tesla. Magnetic field strength is defined as the mechanical force (newton) on a wire of unit length (m) with unit electric current(A). The unit of the magnetic field, therefore, is newton/ (ampere x meter), which is called tesla. The magnetic field may be visualized by magnetic field lines. The field strength then corresponds to the density of the field lines. The total number of magnetic field lines penetrating an area is called magnetic flux. The unit of the magnetic flux is tesla x m2 = weber. The older units for the magnetic flux, maxwell = 10-8 weber, and for the magnetic flux density, gauss = maxwell / cm2 = 10-4 tesla, are not to be used any more. Magnetic flux density diminishes with increasing distance from a straight current-carrying wire or a straight line connecting a pair of magnetic poles around which the magnetic field is stable. At a given location in the vicinity of a current-carrying wire, the magnetic flux density is directly proportional to the current in amperes. If a ferromagnetic object such as a piece of iron is brought into a magnetic field, the "magnetic force" exerted on that object is directly proportional to the gradient of the magnetic field strength where the object is located. -------------------------------------------------------------------

What else can I help you with?
Microwaves in a microwave oven are produced by electrons circling in a magnetic field at a frequency of 2.4GHz. what is the magnetic field strength?
A cavity magnetron is used to produce microwaves in a microwave oven. (See related inks.)Though this involves a magnetic field and an oscillating electron beam, the electrons are not moving in a circle at the cyclotron resonance and this is not the basic mode of operation.
How does one determine the maximum energy to which a deuteron can be accelerated in a cyclotron?
The final energy attained by a deuteron undergoing cyclotron acceleration depends on the design of the cyclotron. In some machines the final energy may be as low as 3MeV whilst in others, 25MeV. Above 25MeV reletavistic effects kick-in and the cyclotron needs to be more sophisticated in its design. It does depend on the cyclotron. Theres actually an equation for that. It takes into account the maximum radius of the orbit of the particles and the wavelength of the accelerating voltage. So for a given cyclotron with exactly specified values for radius and wavelength, the maximum kinetic energy of a particle depends on its rest energy and, hence, its rest mass. But heres an easy way to figure it out: If a given cyclotron can accelerate protons to an energy of say, 2 MeV, then deuterons can be accelerated to 4 MeV. Multiply by a factor of 2.
If the strength of the magnetic field at B is 6 units the strength of the magnetic field at A is?
Since the magnetic field strength decreases with distance from the source (B), the strength of the magnetic field at point A would be less than 6 units. Without additional information, we cannot determine the precise value of the magnetic field strength at point A.
Hall effect can be used to measure?
Hall effect can be used to measure the strength of a magnetic field. When a current passes through a conductor in a magnetic field, a Hall voltage is generated perpendicular to both the current and the magnetic field. By measuring this Hall voltage, the strength of the magnetic field can be calculated.
What instrument measures the strength and direction of magnetic fields?
A magnetometer is the instrument used to measure the strength and direction of magnetic fields. It can be used to detect the presence of magnetic materials or to map out the magnetic field of an object or area.
What is the cyclotron frequency formula used to calculate the frequency of a charged particle moving in a magnetic field?
The cyclotron frequency formula is given by f qB / (2m), where f is the frequency, q is the charge of the particle, B is the magnetic field strength, and m is the mass of the particle.
What is meant by cyclotron frequency?
Cyclotron frequency refers to the frequency at which a charged particle orbits in a magnetic field. It is determined by the strength of the magnetic field and the mass and charge of the particle. The cyclotron frequency is an important parameter in understanding the behavior of charged particles in magnetic fields, such as in particle accelerators.
How do you calculate the pole strength of a magnetic?
The pole strength of a magnetic can be calculated by measuring the magnetic flux that it produces and dividing it by the area of the pole face. The formula to calculate the pole strength is: Pole Strength = Magnetic Flux / Area of pole face.
How to calculate the strength of a magnet?
To calculate the strength of a magnet, you can use a gaussmeter to measure the magnetic field strength in units of gauss or tesla. The higher the measurement, the stronger the magnet.
How to calculate the magnetic field strength around a current-carrying wire?
To calculate the magnetic field strength around a current-carrying wire, you can use the formula B ( I) / (2 r), where B is the magnetic field strength, is the permeability of free space, I is the current in the wire, and r is the distance from the wire.

How do you calculate magnetic fields strength given current and distance away from the wire?
To calculate magnetic field strength near a current-carrying wire, you can use the formula B = (μ₀ * I) / (2 * π * r), where B is the magnetic field strength, μ₀ is the magnetic constant (4π x 10^-7 T*m/A), I is the current in the wire, and r is the distance from the wire. Simply plug in the values and solve for B.
What is the relationship between magnetic energy density and the strength of a magnetic field?
The magnetic energy density is directly proportional to the strength of a magnetic field. This means that as the strength of the magnetic field increases, the magnetic energy density also increases.
What is the relationship between magnetic field strength and distance in a magnetic field?
The relationship between magnetic field strength and distance in a magnetic field is inversely proportional. This means that as the distance from the source of the magnetic field increases, the strength of the magnetic field decreases.
What is magnetic field strength?
Earth's magnetic field strength at the equator is about 30 microtesla.
What is the difference between magnatic field strength and pole strength?
Magnetic field strength refers to the intensity of magnetic field lines in a given area, measured in units of tesla or gauss. Pole strength, on the other hand, refers to the strength of the north or south pole of a magnet, which determines how strong the magnetic field is at that pole. In simpler terms, magnetic field strength is the overall intensity of the magnetic field, while pole strength specifically refers to the strength of individual poles on a magnet.
