Connect the coil to the milliammeter. When placing a permanent magnet (strip or arc-shaped) in a coil-coil

Connect the coil to the milliammeter. When placing a permanent magnet (strip or arc-shaped) in a coil-coil, and then taking it out, notice “when an induction current occurs in the coil
Write down the answers to the following questions.
a) Is there a current in the coil when the magnet and the coil are stationary relative to each other?
b) Does it matter for the induction current that it moves – a magnet or a coil?
c) Does the direction of the induction current change when the magnet is placed inside the coil and when it is removed?
d) How does the strength of the induction current depend on the relative speed of movement of the magnet and the coil: when this speed increases, does the current strength increase or decrease?

a) When the magnet and the coil are stationary relative to each other, there is no current in the coil.
b) And when the magnet moves relative to the coil and when the coil moves relative to the magnet, an induction current appears in the coil
c) The direction of the current in the coil is reversed when removing the magnet from the coil,
d) With an increase in the speed of the magnet relative to the coil, the strength of the induction current increases.
