Question

What is the emf produced in a 1.5 meter wire moving at a speed of 6.2 meters/second perpendicular to a magnetic field of strength 3.96 × 10-3 newtons/amp·meter ?
a.37 volts
b.0.0026 volts
c.5.0 volts
d.0.37 volts
e.0.037 volts

Answer 1

Answer : The correct option is, (e) 0.037 volts

Explanation :

Induced EMF formula :

$e=Blv$

where,

e = emf

B = magnetic field = $3.96\times 10^{-3}Newtons/amp.meter$

l = length of the conductor = 1.5 meter

v = speed of the conductor = 6.2 meter/second

Now put all the given values in the above formula, we get the emf.

$e=(3.96\times 10^{-3})\times (1.5)\times (6.2)=0.037V$

Therefore, the emf is, 0.037 volts
