Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Whether magnetic forces pull apart or push together depends on ____
A
magnetic force
B
magnetic poles
C
magnetic field
D
magnetic field lines
Explanation: 

Detailed explanation-1: -Magnetic forces can be found all around us. Did you know they can be attractive or repulsive? This all depends on the position of the magnets and if the same or opposite magnetic poles are facing each other. The strength of a magnetic force depends on the strength of the magnets and the distance between them.

Detailed explanation-2: -Every magnet has a north pole and a south pole. Placing two unlike poles together causes them to attract. When you try to place two like poles together (north to north or south to south), they will repel each other. The magnets are surrounded by an invisible magnetic field that contains stored-up, or potential, energy.

Detailed explanation-3: -Every magnet produces a magnetic field that is stronger near its poles. If opposite poles of two separate magnets are facing each other, each of the magnets is drawn into the stronger magnetic field near the pole of the other.

Detailed explanation-4: -The magnetic force depends upon the charge of the particle, the velocity of the particle and the magnetic field in which it is placed. The direction of the magnetic force is opposite to that of a positive charge.

Detailed explanation-5: -Unlike poles of different magnets attract each other; like poles repel each other. The magnetic force between a pole of one long bar magnet and that of another was described by an inverse square law as early as 1750.
