The electromagnet

Principle

The students examine the behaviour of a current-carrying conductor that is wound around an iron core (stainless-steel rod), observe that iron-containing objects are magnetically attracted by this set-up and also see that this behaviour is caused by the combination of a coil and iron core, since, separately, both parts exhibit no or only weak magnetic properties.Benefits

• Experiment guides are very easy to understand, especially for younger students
• Associated competences are directly linked to the experiments
• Curriculum compatible
• Fit for the future: implementation of tablets possible
