A current may be induced in a coil by

a) moving one end of a bar magnet through the coil.

b) Moving the coil toward one end of the bar magnet.

c) holding the coil near a second coil while the electric current in the second coil is increasing.

d) all of the above.

e) none of the above.

A bar magnet is positioned near a coil of wire horizontally. What is the direction of the current in the resistor when the magnet is moved (a) to the left and (b) to the right?

Hey how would I solve this?
The coil of wire in a galvanometer has a resistanceofRC = 52.0Ω. The galvanometer exhibitsafull-scale deflection when the current through it is 0.325 mA.Aresistor is connected in series with this combination so astoproduce a voltmeter. The voltmeter is to have afull-scaledeflection when it measures a potential difference of17.7 V. Whatis the resistance of this resistor?
Thank you!
