Gravitational fields and electromagnetic fields are different in that Gravitaional fields are dependent on the masses of objects and the electromagnetic field depends on the charges of objects.
Not really. You could have both an electric field and a magnetic field occupying the same space at the same time but they wouldn't 'make the definition' of electromagnetic until they began to...
Yes, both electric and magnetic fields make up electromagnetic waves. We know that electromagnetic waves (like light) have both an electric and a magnetic component. Both of these components are...
