A magnet is moved close to a rubber band. How does the energy stored in the magnetic field change?
The energy stored in the magnetic field does not change.
The energy stored in the magnetic first increases and then decreases.
The energy stored in the magnetic field decreases
The energy stored in the magnetic field increases.
To determine how the energy stored in the magnetic field changes when a magnet is moved close to a rubber band, we need to understand the relationship between magnetic fields and energy.
The energy stored in a magnetic field depends on the strength of the magnetic field and the volume of space it occupies. The formula for the energy stored in a magnetic field is given by:
Energy = (1/2) * magnetic constant * magnetic field strength² * volume
Now, when a magnet is moved close to a rubber band, the magnetic field around the magnet interacts with the rubber band and induces forces. This interaction does not result in any energy being stored or released into the magnetic field.
Thus, the correct answer is: The energy stored in the magnetic field does not change.
