#20. Why would a wire carrying a current experience a force near a magnetic field?

The copper in the wire is magnetic and naturally experiences magnetic forces in the presence of a magnetic field

The current in the wire creates a magnetic field - this interacts with the other magnetic field, making magnetic forces

#21. Why is the total energy transferred to a kettle’s heating element, more than the total energy of the boiled water inside the kettle?

The total energy transferred to the heating element is difficult to measure and we probably made a mistake

Energy is transferred from the heating element to the rest of the kettle and to the environment

The total energy of the water is less because a little bit of energy is destroyed each time it is moved between stores

If you could accurately measure the movement of energy, you would always find that all of the energy is transferred. Energy cannot be created or destroyed, this is known as the Law of Conservation of Energy.
