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.

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 ...

This is called electromagnetic induction close electromagnetic ... Increasing the speed of the magnet Increasing the strength of the magnet (and the magnetic field) Increasing the number of ...
