Magnetic induction

Principle

A magnetic field of variable frequency and varying strength is produced in a long coil. The voltages induced across thin coils which are pushed into the long coil are determined as a function of frequency, number of turns, diameter and field strength.

Tasks

• Determination of the induction voltage as a function

1. of the strength of the magneticfield,
2. of the frequency of the magneticfield,
3. of the number of turns of the induction coil,
4. of the cross-section of the induction coil.

What you can learn about

• Maxwell's equations
• Electrical eddy field
• Magnetic field of coils
• Coil
• Magnetic flux
• Induced voltage
