I can accurately measure the strength of an electromagnet to analyse how different factors affect it.
Show transcript
A soft iron core increases the strength of an electromagnet because it becomes magnetised when it is turned on.
The more tightly wound the coil of wire is in an electromagnet, the stronger its magnetic field.
The greater the current through the coil of an electromagnet, the stronger its magnetic field.
The strength of an electromagnet is directly proportional to the current through it.
