Question

select the correct answer. what has alternating electric and magnetic fields that travel in the form of a wave? a. electromagnet b. electromagnetic radiation c. alternating current d. direct current e. static electricity

Explanation:

Electromagnetic radiation consists of alternating electric and magnetic fields that travel in wave - like patterns. An electromagnet is a magnet whose magnetic field is produced by an electric current. Alternating current is an electric current that periodically reverses direction. Direct current flows in one direction only. Static electricity is an imbalance of electric charges within or on the surface of a material.

Answer:

B. electromagnetic radiation
