Explanation / Definition:
For this question I don't think we'll have to go deeply into the incorrect options to find out why they're wrong. We'll just get a simple definition of electromagnetism and find what the correct option is:
- Electromagnetism: the interaction of electricity (in the form of currents) with magnets (generation of magnetic fields).
Explanation 2 / Answer explained:
Given the definition above, we can deduce that if there is not current, electromagnetism will not be possible, since there wont be an interaction of electricity and magnetic fields.
