What are magnetic forces used for in everyday life?
magnetic forces are used in magnetic poles
Who discovered the right hand thumb rule?
The right-hand thumb rule, commonly used in physics and engineering to determine the direction of magnetic fields, was popularized by physicist John Ambrose Fleming. Although the concept of using the right hand to visualize vector directions predates him, Fleming formalized it in the early 20th century in relation to electromagnetism. This rule helps in understanding the orientation of forces, fields, and currents in electrical and magnetic systems.
What is alfven number?
The Alfven number is a dimensionless parameter used in plasma physics to characterize the behavior of magnetized plasmas. It compares the inertial forces of a plasma to the magnetic forces acting on it, providing insight into the stability and dynamics of the plasma. Mathematically, it is defined as the ratio of the plasma's flow velocity to the Alfven velocity, which is the speed at which magnetic waves propagate through the medium. High Alfven numbers indicate strong inertial effects relative to magnetic forces, while low values suggest magnetic forces dominate.
What Lorentz force and its application?
The Lorentz force, in electromagnetism, is the effect of electric and magnetic forces which act on a point charge moving through electric and magnetic fields.The Lorentz force can be found in scientific apparatus such as particle accelerators, mass spectrometers and magnetrons. More day-to-day equipment are electric motors, loudspeakers and electrical generators.
Can to magnetic lines of forces touch each other only at single point?
Beats me. But since there ARE no magnetic lines of force, don't worry about it.
Is a negative object attracting a neutral object considered magnetism?
"Negative" and "positive" are terms used with electrical forces, not with magnetic forces."Negative" and "positive" are terms used with electrical forces, not with magnetic forces."Negative" and "positive" are terms used with electrical forces, not with magnetic forces."Negative" and "positive" are terms used with electrical forces, not with magnetic forces.
How are electrical forces like magnetic forces?
In both, opposites attract.
What causes magnetic and electrostatic forces?
friction
Forces that act at a distance?
Those include electrical forces, magnetic forces, and gravitation.
Why are electrical and magnetic forces non contact?
Electrical and magnetic forces are non-contact forces because they can act over a distance without the need for direct physical contact between the objects. These forces are mediated by electric and magnetic fields, which can interact with charged particles or magnetic materials without requiring direct touch.
Which forces can do work on an object?
Any force that causes motion or displacement in an object can do work on that object. Examples include gravitational forces, electrical forces, and magnetic forces. Work is calculated as the force applied to an object multiplied by the distance the object moves in the direction of the force.
What combination causes attraction and repulsive forces?
Electric and Magnetic Forces
Who was the famous who discovered something interesting about electrical and magnetic forces?
Faraday Maxwell
What are the causes of magnetic and electrical forces?
mainly positive and negative charges
What are the two causes of electric and magnetic forces?
Electric forces are caused by the attraction or repulsion of electric charges, while magnetic forces are caused by the motion of electric charges.
How many types of traction systems?
There are generally three main types of traction systems used in transportation: mechanical traction, electrical traction, and magnetic traction. Mechanical traction involves traditional systems like wheels and tracks, commonly seen in trains and vehicles. Electrical traction utilizes electric motors for propulsion, often found in trams, subways, and electric cars. Magnetic traction, such as in maglev trains, uses magnetic forces for lift and propulsion, allowing for high-speed travel with minimal friction.
What are 10 non contact forces?
Gravity, electrical force, magnetic force. These can act with direct touch. "False" forces which are dependent on the observer's motion, such as centrifugal force and g forces are also sometimes considered as non-contact There are also some nuclear forces, but they are not normally observed, and electrical and magnetic forces are really two sides of the same coin.
