What is the difference between the magnetic field of the
bar magnet and
the magnetic field of the solenoid? (also in terms of
how the lines and direction should differ)
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

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.
a) For the zeeman effect what is generally the shape of the
magnetic field between the pole pieces of the electromagnets and
what effect might the shape of the magnetic field have on the
results of this experiment?
b) How would the interference pattern observed for the normal
Zeeman effect (eg with a cadmium lamp) differ from the anomalous
Zeeman effect transition?
How do magnetic field lines from the coil compare with those of
permanent magnet? Explain why they have similar shape. What are the
sources of these magnetic fields?
