Which of the following is incorrect?a)To increase the magnetic strengt...
Magnetic force is a pulling force only: Incorrect

Explanation:
Magnetic force is not only a pulling force but can also be a pushing force. The statement given in option C is incorrect because magnetic forces can attract or repel objects, depending on the poles of the magnets involved.

Magnetic Forces:
Magnetic forces are caused by the interaction between magnetic fields. Magnets have two poles, a north pole and a south pole. Like poles repel each other, while opposite poles attract each other. This means that a north pole of one magnet will repel the north pole of another magnet, and similarly, the south pole of one magnet will repel the south pole of another magnet. On the other hand, the north pole of one magnet will attract the south pole of another magnet, and vice versa.

Examples of Magnetic Forces:
1. When two magnets with opposite poles (north and south) are brought close to each other, they will attract and stick together.
2. Similarly, if two magnets with the same poles (north and north or south and south) are brought close to each other, they will repel and push each other away.

Application Examples:
Magnetic forces have various applications in our daily lives, such as:
1. Refrigerator magnets: They use magnetic force to stick to the surface of the refrigerator.
2. Magnetic door catches: These use magnetic force to hold doors in place.
3. Magnetic levitation trains: They utilize magnetic forces to achieve levitation and propulsion.

Conclusion:
In conclusion, magnetic forces are not limited to just pulling objects together. They can also push objects apart, depending on the orientation of the magnetic poles involved.
