Problem Details

You hold a wire coil so that the plane of the coil is perpendicular to a magnetic fieldB_vec.

If the magnitude ofB_vecincreases while its direction remains unchanged, how will the magnetic flux through the coil change?

Check all that apply.

a) The flux is unchanged because the position of the coil with respect toB_vecis unchanged.

b) The flux increases because the magnitude ofB_vecincreases.

c) The flux decreases because the magnitude ofB_vecincreases.

d) The flux is unchanged because the surface area of the coil is unchanged.
