The presence of a magnetic force field may be detected by using
- a. a compass.
- b. iron filings.
- c. a magnet.
- d. all of the above.
Find the right option.
Answer to Problem 1RQ
The right option is “d. all of the above”.
Explanation of Solution
The magnetic force is the force of attraction or repulsion which arises between the electrically charged particles because of its motion.
If the bar magnet is free to rotate, it will rotate until one end points to the south pole and other end points to the north pole, where the points are named as south-seeking and north-seeking pole. If the same poles of the two magnets are brought near, it creates repulsion. In general, same poles repel each other and opposite poles attract each other.
The presence of a magnetic force field may be detected by using:
- (1) A compass.
- (2) An Iron filing.
- (3) A magnet.
A compass is a device which is structured as a small magnetic needle and it tends to rotate freely on the bearing. The compass device can detect the presence of the magnetic force field.
The magnetic field can also be found by using the iron filings. The iron filing is actually two-dimensional but the field around the magnet can be viewed as three-dimensional.
The magnetic force near the electric current or the magnetic pole can also be detected by using a magnet.
Therefore, the presence of a magnetic force field may be detected by using a compass, iron filings, and a magnet.
Conclusion:
Hence, the correct option is “d. all of the above”.
