It believe it is under the ground because it normally is in tunnels
The superconducting magnets are able to generate powerful magnetic fields because they have no electrical resistance.
To find the answer, we have to know more about the superconducting magnets.
<h3>What is superconducting magnet?</h3>
- An example of an electromagnet is a superconducting magnet.
- They are constructed from coils of superconducting wire and must be used while being chilled to cryogenic temperatures.
- Because the wire encircling the magnet has no electrical resistance when it is in its superconducting condition, they may produce powerful magnetic fields.
- Because of this, the magnet can conduct far greater electrical currents than the typical electromagnet.
Thus, we can conclude that, the superconducting magnets are able to generate powerful magnetic fields because they have no electrical resistance.

Answer:
This is not a question, but a statement. The concept that the work done is equal to the input work on a simple machine is called ideal machine. An ideal machine has 100% efficiency which means that there is no loss. All the amount of input work is equal to the useful output of the machine.

Explanation: Here is a link to a video that might help you
1,000 grams = 1 kilogram
20 grams = 0.02 kilogram
Kinetic energy = (1/2) (mass) x (speed)²
(1/2) (0.02) x (15)² =
(0.01) x (225) = 2.25 joules
