Two circular current-carrying loops of wire are shown in the drawing. The inner loop has a radius of R0 and carries a current I0, while the outer loop has a radius of 2R0 and carries a current of 4I0. The currents are in opposite directions. If R0 = 0.20 m and I0 = 2.3 A, determine the magnitude and direction of the net magnetic field at the center of the two loops.

3. A coil consists of 130 circular loops of wire of radius 4.4 cm. A current of 0.46 A runs through the coil, which is oriented vertically and is free to rotate about a vertical axis (parallel to the z-axis). It experiences a uniform horizontal magnetic field in the positive x-direction. When the coil is oriented parallel to the x-axis, a force of 1.2 N applied to the edge of the coil in the positive y-direction can keep it from...

The figure shows two parallel loops of wire having a common axis. The smaller loop (radius r) is above the larger loop (radius R) by a distance x >> R. Consequently, the magnetic field due to the counterclockwise current i in the larger loop is nearly constant throughout the smaller loop. Suppose that i, the current in the larger loop is shut off, and decreases at the constant rate di/dt. R in the smaller loop, find (c) the direction of...

A) A 190–turn circular loop of radius 58.0 cm is vertical, with its axis on an east–west line. A current of 90.0 A circulates clockwise in the loop when viewed from the east. The Earth’s field here is due north, parallel to the ground, with a strength of 3.30×10-5 T. What is the magnitude of the torque on the loop? (Does this device have any practical applications as a motor?) B) What is the direction of the torque on the...

The figure shows two parallel loops of wire having a common axis. The smaller loop (radius) is above the larger loop (radius R) by a distance x >> R. Consequently, the magnetic field due to the counterclockwise currenti in the larger loop is nearly constant throughout the smaller loop. Suppose that r, the radius of the smaller loop is increasing as the loop heats up, at the constant rate dr/dt. R in the smaller loop, find (c) the direction of...

In Figure (a), two circular loops, with different currents but the same radius of 40 cm, are centered on a y axis. They are initially separated by distance L-3.0 cm, with loop 2 positioned at the origin of the axis. The currents in the two loops produce a net magnetic field at the origin, with y component By That component is to be measured as loop 2 is gradually moved in the positive y direction. Figure (b) gives By as...
