The bigger the current the stronger the magnetic field and hence the stronger the electromagnet. Hazard Consequence Control measures Water Electric shock Do not set up the experiment near taps ...

The small electromagnets which are commonly used by oculists often fail at the critical moment, owing to their lack of adequate magnetic strength, and thus endanger the success of the operation.

For all the one-minute-abs routines and muscle-zapping electromagnetic (EMS) classes I've tried, there is one bodyweight ...

A second experiment can be carried out to investigate how the strength of the electromagnet depends on the number of turns in the coil. As the number of turns increases the number of paper clips ...

The magnetic field around a single wire is very weak. Coiling the wire around an iron core increases the strength of the electromagnet by concentrating the magnetic field. In this activity campers ...
