Magnets Flashcards
1
Q
MAGNETIC FIELD
(B) OF A CURRENT CARRYING WIRE?
A
The current-carrying
wire should be very
long and straight.
2
Q
ELECTROMAGNETS
A
Current moving through a wire creates a
magnetic field around the wire.
▪ More coils makes a stronger magnet
3
Q
ELECTROMAGNETIC
INDUCTION
A
Moving charges in the coil create an electric current, which induces voltage. More loops in the coil result in higher voltage.
4
Q
GENERATORS: AC AND DC – I?
A
▪ Mechanical energy to electric energy
