What are the two types of fields Electric fields and magnetic fields.
discussed in electromagnetism?
What is the significance of the Right It is used to determine the direction of force on a
Hand Palm Rule? charged particle in a magnetic field.
What does Faraday's Law describe? It describes how a change in magnetic flux can induce
an electromotive force (EMF) in a circuit.
What is Lenz's Law? It states that the direction of induced current will
oppose the change in magnetic flux that produced it.
What is the definition of magnetic flux? Magnetic flux is the product of the magnetic field
strength and the area perpendicular to the field.
What is the motor effect? The motor effect refers to the force experienced by a
current-carrying conductor in a magnetic field.

What is the formula for calculating the F = BIL sin(θ), where F is the force, B is the magnetic
force on a conductor in a magnetic field strength, I is the current, and θ is the angle
field? between the field and the conductor.
What is an AC generator? An AC generator converts mechanical energy into
electrical energy using electromagnetic induction.
What is a step-up transformer? A step-up transformer increases voltage while
decreasing current.
What is a step-down transformer? A step-down transformer decreases voltage while
increasing current.
What is back EMF? Back EMF is the voltage generated by a motor that
opposes the applied voltage when the motor is
running.
What happens to back EMF when a Back EMF decreases, allowing more current to flow to
load is introduced? meet the load demand.
What are eddy currents? Eddy currents are loops of electric current induced
within conductors by a changing magnetic field.
What is the effect of resistive heat It leads to energy losses during power transmission.
