A wire bent with two right angles (forming a u-shape) sits in the xy-plane. The closed end (where the right angles are) is on the x-axis.

A wire bent with two right angles (forming a u-shape) sits in the xy-plane. The closed end (where the right angles are) is on the x-axis. The sides parallel to the y-axis run in the -y direction. A movable wire, parallel to the x-axis but not on the x-axis at any time, moves in the +y direction. If a magnetic field going in the -z direction baths the circuit, what is the direction of the induced current in the movable wire?

Solutions

Expert Solution

When the wire is moved in +y direction the flux linked with the loop goes on decreasing as the area shrinks, to oppose this a current is induced in the loop which is clockwise in direction. But here, it is asking about the direction of induced current in the movable wire. So the direction of induced current in the movable wire is towards the -x-direction.

Consider two long wire with negligible resistance closed at one end of the resistance R (say a light bulb), and the other end connected to a battery (DC voltage). Cross-sectional radius of each wire is in x=100 times smaller than the distance between the axes of the wires. Question: At which value of resistance R (in ohms) the resultant force of the interaction of parallel conductors disappears?
