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?
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.
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)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 magnet moves as shown. The field of the magnet through the coil is
to the left and the primary flux through the coil is decreasing.
to the right and the primary flux through the coil is decreasing.

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)
How are the properties of magnetic field lines similar to the
properties of electric field lines?How are they different? (at
least three for each) Thanks for your help.
A permanent magnet is held directly below the center of
a coil which is connected to a voltmeter. As you move the magnet
closer towards the coil, the voltmeter reads negative. Which of the
following statements is always true?
Moving the magnet farther away from the coil would produce a
positive voltage reading instead.
Moving the magnet farther away from the coil would also produce
a negative voltage reading.
The closer to the coil the magnet is held in place,...
