PREVIOUS ANSWERS

The magnetic field created by a large current passing through plasma $($ionized gas$)$ can force current$-$carrying particles together. This pinch effect has been used in designing fusion reactors. It can be demonstrated by making an empty aluminum can carry a large current parallel to its axis. Let $R$ represent the radius of the can and I the current, uniformly distributed over the can's curved wall.

$($a$)$ Determine the magnetic field just inside the wall. $($Use any variable or symbol stated above along with the following as necessary: ${}_0.)$

$($b$)$ Determine the magnetic field just outside. $($Use any variable or symbol stated above along with the following as necessary: ${}_0.)$

tangent to the wall

$($c$)$ Determine the pressure on the wall. $($Use any variable or symbol stated above along with the following as necessary: ${}_0.)$
