If the magnetic field is uniform over the area bounded by a circle with a radius R, the net current through the circle is?
A) 0
B) 2(pi)RB u0
C) (pi)R 2 B/ u0
D) RB/2u0
E) 2RB/ 0
Homework Answers
Ans: (A) 0
Since the magnetic field is uniform, there is no change of flux through the circle and hence the net current is zero. This is because we know that current will be induced only when there is a change of flux.
Here the magnetic field is uniform and thus there is no change of flux.

3 The magnetic field inside a toroidal solenoid is not uniform as for the long, straight solenoid. Over the cross-sectional area of the toroid the magnetic field is stronger near the inner HoNI radius of the torus and somewhat weaker near the outer radius according to B(r) 2Tr So we cannot technically use the simple expression P2 = BAfor the flux through one turn of wire. Nevertheless, the textbook uses an approximate constant value for an equivalent uniform magnetic field...

A circular loop of wire with radius R is in a uniform magnetic field with magnitude B that points in the positive z-direction. The loop is initially in the xy-plane and carries a constant, unknown current. Flipping the loop over requires you to do positive work (W). Determine the current in the loop.
