Magnetic field vs current in a solenoid: collect your own data

Описание: This short video shows the strength of the magnetic field (B) at the end of a solenoid as a function of the current (I) through it. It give a beautiful linear relationship as expected from the solenoid formula B = unI. Students can collect their own data from this read experiment and analyse it for a report.
