Questions & Step-by-Step Solutions
What is the effect of increasing the speed of a magnet moving through a coil?
Steps
Concepts
Step 1: Understand that a magnet has a magnetic field around it.
Step 2: Know that a coil is made of wire and can detect changes in magnetic fields.
Step 3: When a magnet moves through the coil, it changes the magnetic field inside the coil.
Step 4: The faster the magnet moves, the quicker the magnetic field changes.
Step 5: This change in the magnetic field is called 'magnetic flux.'
Step 6: According to Faraday's law, a change in magnetic flux induces an electric current in the coil.
Step 7: Therefore, increasing the speed of the magnet increases the rate of change of magnetic flux.
Step 8: As a result, a faster magnet creates a stronger induced current in the coil.
