Question

Fig. shows a car stuck to an electromagnet. Name the forces acting on the car?

A. Gravitational force due to earth
B. Magnetic force due to electromagnet on car.
C. Electrostatic force
D. No force acts on the car

Answer 1

An electromagnet is a magnet whose magnetic field is generated by an electric current. Wire coiled into a coil is used to make electromagnets. A current flowing through the wire produces a magnetic field that is focused in the hole, which serves as the coil's core.

Complete answer:
Gravity, or gravitation, is a natural phenomena in which all things with mass or energy attract toward one another, including planets, stars, galaxies, and even light. Gravity gives tangible items weight on Earth, while the Moon's gravity creates ocean tides. All bodies on Earth have a weight, or downward force of gravity, proportionate to their mass, which is exerted on them by the Earth's mass.

The acceleration that gravity imparts to freely falling objects is used to quantify gravity. The magnetic impact on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field. In a magnetic field, a moving charge experiences a force that is perpendicular to both its own velocity and the magnetic field.

The magnetic field of a permanent magnet attracts or repels other magnets, as well as ferromagnetic elements like iron. Furthermore, a varying magnetic field exerts a force on a variety of non-magnetic materials by changing the mobility of their outer atomic electrons.
Electromagnetic force operates vertically upward on the automobile, whereas gravitational force operates lower downhill.

Hence option A and B are correct.

Note: The force of attraction is a force that attracts the body closer together.Magnetic force, electric force, electrostatic force, and gravitational force are some of them. The gravitational pull is a well-known example of attraction since it attracts things to itself regardless of their distance.
