Question

A 0.200 m wire is moved parallel to a 0.500 T

magnetic field at a speed of 1.50 m/s. What emf is
induced across the ends of the wire?

Answer 1

The required emf moved across the wire is zero

Step-by-step explanation:

For a moving charge particle, the magnetic force can be determined by using the formula;

`\varepsilon = Bvlsin \theta`

since the wire moves in parallel, the angle
`\theta` between magnetic field and velocity = 0°

B = 0.500 T

v = 1.50 m/s

l = 0.200 m

∴

`\varepsilon = (0.500 \ T )(1.50 \ m/s) * (0.200 \ m)* sin (0)`

`\varepsilon = 0.15* sin (0)`

`\varepsilon = 0`
