Current vs, magnetic field. (Physics (11-14) eBook)
A fixed size coil has current is passed through it. The induced magnetic field is measured for each current. The relationship between current and magnetic field strength can be studied.

Electromagnets : What happens if you use an alternating current in an electromagnet coil? (Physics (14-18) : Electricity & Heat eBook)
Passing an alternating current through an electromagnet will produce a powerful non permanent magnet. Why would this be an advantage? why is magnetic permanence reduced?

How does the magnetic field change along the axis of a coil? (Physics (14-18) : Electricity & Heat eBook)
This investigation will allow the students to understand the way the field changes along the axis of a coil. It uses the EASYSENSE software’s Snapshot facility with a function that asks the user for a value (in this case the distance) after each data collection.
