Question

A 10 ohm resistance coil has 1000 turns it is placed in a magnetic field of magnetic induction 5×10^-4 tesla in 0.1 second. If area of cross section is one square metre, then the average induced emf is

Answer 1

Data:

• R=10 OHM

• N=1000

• MAGNETIC FIELD=5×10^-4 tesla

• T=0.1SECOND

• A=1M^2

• INDUCED EMF=?

Formula:

Induced EMF = (Number of turns x Magnetic field x Area)/change in Time.

N * A * B / (T)

1000 * 1* 5×10^-4 / ( 0.1 ) = 5

Answer  

Induced emf is equal to 5 volt

Answer 2

Answer:

Data:

R=10 OHM

N=1000

MAGNETIC FIELD=5×10^-4 tesla

T=0.1SECOND

A=1M^2
