Which statements best describe magnetic fields? check all that apply. a magnetic field is the area around a magnet where a force is exerted on certain objects. a magnetic field is an area of land where magnets are found. magnetic field lines are strongest around the middle of the magnet. magnetic field lines spread out of the north end of the magnet. magnetic fields are three-dimensional and resemble a bubble.

The correct answers are "A magnetic field is the area around a magnet where a force is exerted on certain objects", "Magnetic field lines spread out of the north end of the magnet" and "Magnetic fields are three-dimensional and resemble a bubble".

Explanation:

Three statements that define a magnetic field are:

1. "A magnetic field is the area around a magnet where a force is exerted on certain objects". Magnetic field force is driven by moving electric charges and the objects that are susceptible to the forces are known as electromagnetic objects.

2."Magnetic field lines spread out of the north end of the magnet". Magnetic fields are taken to be outward from the North pole to the South Pole. This direction takes place on Earth as well, because Earth function as a giant magnet.

3. "Magnetic fields are three-dimensional and resemble a bubble". Magnetic field forces are driven following a bubble like configuration and affects the objects upon this configuration.
