Multiple Choice

The magnetic reed switch will only detect the presence of a(n) ______ object.

Explanation:
A magnetic reed switch is activated by a magnetic field. It contains two ferromagnetic reeds sealed in a glass capsule; when a magnet (or an electromagnet) brings a magnetic field near them, the reeds attract each other and close the circuit. Because the sensing mechanism relies on detecting a magnetic field, it responds to a magnetic object or magnet nearby, not to ordinary metallic, electrical, or optical presence. Some metals can be influenced by a magnet, but the switch’s action specifically requires a magnetic field, which is why the magnetic option is the correct choice.
