GEOLOGY

Detailed explanation-1: -Again, you could increase the potential energy by moving the magnets opposite the direction of the magnetic force. For example, by pulling apart a North Pole and a South Pole.

Detailed explanation-2: -Answers: If the bar magnet is moved farther from the electromagnet the potential energy will decrease. If the bar magnet is moved closer to the electromagnet the potential energy will decrease.

Detailed explanation-3: -The potential energy can be increased by increasing the mass of the object, by varying the distance between the two objects, decreasing the kinetic energy of the molecules, by freezing, by compressing or stretching, etc.

Detailed explanation-4: -Answer and Explanation: You can increase the magnetic field strength of a magnet by increasing the current flow through the wires of the magnet. If this is an electromagnet with coiled wires around a central rod or core, increasing the number of coil turns on the core will also increase the magnetic field.

Detailed explanation-5: -Magnetic potential energy is energy stored in a system of magnets as a result of the exertion of a magnetic force on each other. When two magnets attract or repel each other potential energy can be stored in their relative positions.
