Physics for IGCSE & O level - Magnets And Currents (Section 9 - No. 30)
What happens to a magnet when pushing a magnet in a coil, which way does the induced current in the coil flow?
The current increases with the speed of the magnet's movement and the direction of induced current depends on the pole pushed into the coil.
The current decreases with the speed of the magnet's movement and the direction of induced current depends on the pole pushed into the coil.
The current is not changing, and the direction of the current flow is not dependent of the direction of movement
The current is not changing and the direction is dependent of the speed of the magnet's movement
Explanation
The direction of the induced current changes if the direction of movement changes, or if the polarity of the magnet changes. And the current magnitude is directly linked to how fast the magnet is moved.
