A coil of area 2 m is placed in magnetic field changing from 4 to 8 in 2 sec find the induced emf

ProBeast513: 2 volts

terenaam1234: show me ur soln

ProBeast513: U r in which class?

ProBeast513: Do u know Flux?

terenaam1234: plz show me ur soln just

ProBeast513: U won't understand if u Don know flux

terenaam1234: dont give xplanation show me how u get ur answer

ProBeast513: Ok

ProBeast513: Sry it is 4v

Emf produced in circuit = delta flux/ delta time

Flux = BA COSthetha.
So, as the B(magnetic field) changes from 4 to 8, and angle of area vector n motion is same,
Flux initial is 4*2 wb
Flux final is 8*2 wb

Thus delta Flux is 8wb, n time is 2 sec.
So Emf is 4 volts
