What is the Hall effect?
If a semiconductor carrying a current ( I ) is placed in a transverse magnetic field ( B ), an electric field ( E ) is induced in the direction perpendicular to both I & B.This is called hall effect.for full explanation visit http://www.ecematerials.com/2013/07/hall-effect.html
What are 3 factors which affect the magnitude of magnetic force on current-carrying conductors?
Electric current, magnetic field intensity, length of the conductor, angle between the electric current and magnetic field
What is the term used to express the amount of electrical current stored in an electrostatic field?
Pie
What is the purpose of inductor?
The fundamental purpose of an inductor is to store electrical energy in a magnetic field.
Does the magnetic field increase or decrease if the current is decreased?
An increase in an electrical current will cause magnetism to increase but a decrease in an electrical current will cause magnetism to decrease.
What are equipotential lines?
A uniform electric field exists between parallel plates of equal but opposite charges.
What is Equipotential lines in electric field?
Equipotential lines are lines that are perpendicular to the lines representing the electric field of a particle. A particle can travel freely of equipotential lines without doing any work.
Why must electric field line be perpendicular to equipotential surfaces?
If the field lines were not perpendicular to the surface, then they could be decomposed into components perpendicular and parallel to the surface. But if there is an E-field along the surface, the surface is no longer an equipotential.
Why is it important for an electromagnet field to flip halfway through the turn of the motor axle?
The angle when the field changes is determined by the angle between coils. For any electrical motor to continue to rotate the field has to move, otherwise the rotor North would reach the stator South and stop.
What is the relations between electrical field and electrical potential?
The electrical field E = - dV/dr, the derivative of the electrical potential, V.
How are gravitational field and an electrical field similar?
The electrical field force acts between two charges, in the same way that the gravitational field force acts between two masses.
Why are the equipotential lines near conductor surfaces parallel to the surface?
For conductors, the electric field perpendicular to its surface and no field exist within the conductor. As a result the equipotential lines are found near the surface. They are parallel to the surface since equipotential are perpendicular to field lines.
Why is sine wave used in electrical voltage generation?
It isn't as such, it is a consequence of generating electricity using a rotary method - the voltage generated is proportional to the sin of the angle between the magnetic field and the coil, and the angle changes due to rotation.
What is the relationship between electrical frequency and magnetic field speed for an ac machine?
What is the relationship between electrical frequency and magnetic field speed for an ac machine
What is the difference in electrical potential energy between two places in an electrical field?
voltage

What is the definition of the word permittivity?
A measure of ability of a material tro resist the formation of electrical field within it equal to ratio between electrical flux density and electrical field strength generated by an electrical charge on the material. It is defined by permittivity.
