Q: Describe an activity to show that an electric current carrying wire behaves like a magnet?
Answer :-
A current passing through a wire generates a magnetic field. This is explained by special relativity. Similar to the combination of space and time into the four-component spacetime vector magnetic and electric field are combined into the electromagnetic tensor. Changing reference frames mixes the components between electric and magnetic field.
You can say one electron in its reference frame just observes his electric field. but a passing, second electron sees this partially as a magnetic field.
