Magnetism

When current is induced in such a conductor, the induced current often flows in small circles that resemble eddies in a stream. These electrical currents were named eddy currents. In the following science experiment, we you can demonstrate how...

In this science experiment, you will suspends some iron filings in mineral oil to allow you to see a more realistic representation of the lines of magnetic force.

Extreme heat can destroy magnetism whereas extreme cold can make a magnetic field stronger. Test the effect extreme temperatures has on soft iron magnets in this science experiment.

In this science experiment we will compare the magnetic attraction of rusty iron filings with regular iron filings, by comparing the weight of each type of filings that can be picked up by a magnet at once.

The strength of the new magnet is determined by how many times it is stroked with the permanent magnet, and if a nail is only stroked a few times with a permanent magnet, it will only have a very...

Electrical current can only flow when there is a difference in electrical potential, not when they are alike. Observe what happens when electrical current is induced with the south and the north pole of a magnet respectively in this...

In this science experiment we will be making a compass with a simple steel sewing needle, by magnetising it.

You can have a lot of fun by making a 'sail' boat that is invisibly driven by magnetic power. In this science experiment we will be making a boat that can 'sail' even when there is no wind power!

A piece of steel or steel nail can also be turned into a 'permanent' magnet by stroking it several times with another strong permanent magnet as you will see in the following science experiment.

In this science experiment we will be making magic and having fun with magnets and the laws of magnetism. We will be making two magnets float on top of each other without touching!
