Like poles on a magnet ?
attract
repel
none of the above
both a & b
What is electromagnetic induction?
the process of charging a body
The process of rotating a coil of an electric motor.
producing induced current in a coil due to relative motion between a magnet and the coil
The process of generating magnetic field due to a current passing through a coil.
Who showed that an electric current can be produced in an conductor with the help of moving magnet ???
Albert Einstein
Issac Newton
Michael Faraday
Homi J. Bhabha
The Direction of the current flowing through the conductor in perpendicular to the magnetic field, then a force is exerted on the (a) .
What is that instrument which can detect the presence of electric current in a circuit?
galvanometer
motor
generator
None of the following
What can electromagnets do that regular magnets can't?
Explode
No difference , both are the same
Burn
Switch their magnetic fields
What is the consequence/result of motor effect ?
current
electromotive force
electromagnetic induction
voltage
If the solenoid coil is moved towards or away from the coil, we see a deflection in the (a) .
Even if the solenoid coil is kept stationary, a change in current in the solenoid coil produces a (a) in the coil
Can you produce current in a wire with a magnet that is sitting still?
Yes; having a magnet near a wire is enough to excite the electrons
No; the magnetic field has to be changing to excite the electrons
No; magnets cannot create electricity
None of the following
