Question

What discovery by Ørsted led to the development of electromagnets? A Electric currents produce magnetic fields. B Magnetic fields produce electric currents. C Magnets produce electricity. D Magnets produce heat.

Answer 1

Answer: a. Electric current produces magnetic field

Explanation: Ørsted discovered that the passage of steady electric current through a wire creates a magnetic field around it.

His discovery marked the first connection between electricity and magnetism.

Answer 2

A. Electric currents produce magnetic fields.

Step-by-step explanation:

Answer:

A. Electric currents produce magnetic fields.

Step-by-step explanation:

Hans Christian Ørsted discovered that electric currents had a property of producing magnetic fields. This finding was the first established relationship found between electricity and magnetism.

He noticed that a compass deflected when current was switched on and off and this marked the first established relationship between electricity and magnetism.
