Case Study Questions
I. A magnetic compass is usually a small circular box with a transparent cover on it, as shown in the figure. The magnet, in the shape of a needle, is mounted on a pin standing on the bottom of the box. This needle is balanced on the pin in such a manner that it can move around this point easily, that is, it can rotate freely. The end of the needle, which rests in the North direction, is usually painted red. Below the needle, there is a dial with directions marked on it.
1. What is the primary function of a magnetic compass?
(а) To measure temperature
(b) To measure time
(c) To indicate direction
(d) To measure distance
Answer:
(c) To indicate direction
2. Which of the following is NOT a part of a magnetic compass?
(a) Needle
(b) Dial
(c) Glass cover
(d) Thermometer
Answer:
(d) Thermometer
3. What happens when we place a bar magnet near the magnetic compass?
(а) The needle points towards the magnet
(b) The needle points away from the magnet
(c) The needle remains stationary
(d) The needle spins randomly
Answer:
(а) The needle points towards the magnet
4. The limitation of a magnetic compass is:
(а) It can be used only indoors.
