Electromagnetic induction Flashcards
1
Q
If a conductor is moved so as to cut across magnetic field line, then a current will be
A
Induction
2
Q
Current flows only while th movement is
A
Taking place
3
Q
Current can be increased by (2 things)
A
1- using a stronger magnet
2- moving the conductor or magnet more quickly
4
Q
The directiom of the current is reversed if the direction of moment is
A
Reversed
OR The magnets of the poles are reversed
5
Q
No current will flow when the magnet is totally …… The coil
A
Inside
6
Q
The side of the induced current increases with;
A
1- increasing speed of motion
2- strength of magnet
3- number of turns in the coil
7
Q
The directiom of the induced current reverses if;
A
1- the magnet is reversed
2- the direction of motion is reversed
