Question

A magnetic field of magnitude 0.340 T is oriented perpendicular to the plane of a circular loop. HINT (a) Calculate the loop radius (in m) if the magnetic flux through the loop is 2.65 Wb. (b) Calculate the new magnetic flux (in Wb) if the loop radius is doubled. Wb Need Help? Read It

Answer 1

a)

let the loop radius is r

for the magnetic flux = area * magnetic field

2.65 = 0.340 * pi * r^2

r = 1.58 m

the loop radius is 1.58 m

b) for doubling the radius ,

the area of the loop will be 4 times

new magnetic flux = 4 * 2.65

new magnetic flux = 10.6 Wb

the new magnetic flux is 10.6 Wb
