Magnetism and electromagnetism

Question 1

State examples of how the magnetic effect of a current can be demonstrated
and explain how a solenoid arrangement can increase the magnetic effect of the
current

Question 2

Draw the magnetic field pattern for a straight wire carrying a current and for a
solenoid (showing the direction of the field)

Question 3

HT ONLY: State and use Fleming’s left-hand rule and explain what the size of
the induced force depends on

Question 4

HT ONLY: Calculate the force on a conductor carrying a current at right angles
to a magnetic field by applying, but not recalling, the equation: [ F = BIL ]
