GEOLOGY

Detailed explanation-1: -Electricity and magnetism are closely related. Flowing electrons produce a magnetic field, and spinning magnets cause an electric current to flow. Electromagnetism is the interaction of these two important forces.

Detailed explanation-2: -Electricity can be present in a static charge, while magnetism’s presence is only felt when there are moving charges as a result of electricity. In simple words, electricity can exist without magnetism, but magnetism cannot exist without electricity.

Detailed explanation-3: -Until electromagnetism was discovered, scientists thought that electricity and magnetism were unrelated. A Danish scientist named Hans Christian Oersted changed all that. He discovered that electric current in a wire can deflect a magnetized compass needle that means electric current creates a magnetic field.

Detailed explanation-4: -Electricity and magnetism are closely related: power lines generate a magnetic field and rotating magnets in a generator produce electricity. But the phenomenon is actually much more complicated, because the electrical and magnetic properties of certain materials are also coupled with each other.

Detailed explanation-5: -Answer: Electricity and magnetism are intimately linked: a changing magnetic field will induce a current in a wire and a moving current such as down a wire, produces a magnetic field around it.
