A bar magnet is oriented perpendicular to a uniform magnetic
field as shown in . Describe the force and/or torque on the
magnet.
There is a net torque on the magnet in a clockwise
direction.
There is a net torque on the magnet in a counterclockwise
direction.
There is a net force on the magnet opposite to the direction of
the magnetic field (towards the top of screen).
There is a net force on the magnet in the direction of...

A)Draw the direction and rough shape of magnetic field lines
coming from a bar magnet
B)A charged particle (your choice of charge) moving at a
velocity v enters a magnetic field having a
magnetic field density B. Draw a picture showing
how the "Right-Hand-Rule" works in this case.
The magnetic field inside a superconductive magnet is 6T. The
length of the coil body is l = 30cm and the diameter d = 2cm. The
coil is made of 1km long cable of a superconductive Nb-Ti alloy and
is found surrounded by liquid Helium (T=4.2K) and therefore in the
superconductive phase.
a) Determine the number of windings
b) Determine the current in the coil
c) Determine the electrical Power required

A short bar magnet placed with its axis at 30° with a uniform external magnetic field of 0.25 T experiences a torque of magnitude equal to \( 4.5\times 10^{-2}\; J \). What is the magnitude of the magnetic moment of the magnet?
Describe how a magnetic field is generated by simply moving a
magnet relative to a coil. Please be sure to use an equation to
help you explain the physics! Thank you.
Q1: What is the difference between bar drawing and deep
drawing? What is the difference between a cutoff
operation and a parting operation? Distinguish between direct and
indirect extrusion. Although the workpiece in a wire drawing
operation is obviously subjected to tensile stresses, how do
compressive stresses also play a role in the process?
