Important Questions from Electromagnetism
Which of the following can produce a magnetic field?
Show answer
Bar magnet, Current-carrying wire, Moving electric charge, Solenoid with current
Magnetic fields are produced by magnets, moving charges (current), and current-carrying conductors. A stationary charge does not produce a magnetic field.
Which components are essential for an electric motor?
Show answer
Current-carrying coil, Commutator, Carbon brushes
An electric motor needs a magnet to provide magnetic field, a coil to carry current, a commutator to reverse current direction, and brushes for electrical contact. A galvanometer is used for current measurement, not in motors.
According to Lenz's law, the direction of induced current is such that it:
Show answer
Opposes the change in magnetic flux
Lenz's law states that the induced current flows in such a direction that it opposes the change in magnetic flux that produced it. This is based on conservation of energy.
Which factors affect the magnitude of induced EMF in a coil?
Show answer
Number of turns in coil, Rate of change of magnetic flux, Strength of magnetic field, Area of the coil
According to Faraday's law, induced EMF depends on the number of turns, rate of change of flux, field strength, and coil area. Resistance affects current but not the induced EMF itself.
