A magnetic dipole is falling in a conducting metallic tube
A magnetic dipole is falling in a conducting metallic tube. Consider the induced current in an imaginary current loop when the magnet is moving away from the upper loop and when the magnet is moving toward the lower loop.
Determine the directions of the induced current Iabove in an imaginary loop shown in the figure, as viewed from above, when the loop is above the falling magnet and the direction of the induced magnetic dipole moment μind.

Conceptual: A conducting loop of wire is oriented horizontally, and a magnet is falling downward, through the loop. (a) Draw the direction of the induced current that flows in the loop as the magnet falls downward. (b) Sketch and label the magnetic field lines that are created by the induced current in the loop. (c) Does this create an attractive or repulsive force between the loop and magnet?

You have a piece of copper (conductivity = 6.0*10^7 Ω^-1m^-1) wire 26 cm long and 2.0 mm in diameter and a bar magnet with a magnetic dipole moment of 0.75 Am^2. You decide you’re going to make use of...
You have a piece of copper (conductivity = 6.0*10^7 Ω^-1m^-1) wire 26 cm long and 2.0 mm in diameter and a bar magnet with a magnetic dipole moment of 0.75 Am^2. You decide you’re going to make use of induction to make some current flow in the wire. First, you pull the copper wire into a circular loop. Then you hold the bar magnet 15 cm above the center of the loop, parallel to the loop so that there is...
