What is a magnetic force Kid definition?
Magnetism is the force of attraction or repulsion between substances made of certain materials, such as iron, nickel, cobalt, and steel.
The force of magnetism, simply put, is due to the motion of electric charges.
Magnets are present in most electronic devices.
In fact, anything that has a motor uses a magnet..
What is magnetic force Class 9?
Magnetic force is a consequence of electromagnetic force and is caused due to the motion of charges. We have learned that moving charges surround itself with a magnetic field. With this context, the magnetic force can be described as a force that arises due to interacting magnetic fields.
What are the 4 magnetic metals?
Magnetic metals include:Iron.Nickel.Cobalt.Some alloys of rare earth metals.
How do we use magnetic force in everyday life?
Computer hard drives use magnetism to store the data on a rotating disk. More complex applications include: televisions, radios, microwave ovens, telephone systems, and computers. An industrial application of magnetic force is an electromagnetic crane that is used for lifting metal objects.
What is magnetic strength?
Magnetic field strength, also called magnetic intensity or magnetic field intensity, the part of the magnetic field in a material that arises from an external current and is not intrinsic to the material itself. It is expressed as the vector H and is measured in units of amperes per metre.
What is meant by magnetic field?
A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. … Magnetic fields surround magnetized materials, and are created by electric currents such as those used in electromagnets, and by electric fields varying in time.
What is magnetic field and its unit?
The SI unit for magnetic field is the Tesla, which can be seen from the magnetic part of the Lorentz force law Fmagnetic = qvB to be composed of (Newton x second)/(Coulomb x meter). … A smaller magnetic field unit is the Gauss (1 Tesla = 10,000 Gauss).
What is magnetic force explain with example?
This force causes the magnets to attract or repel one another. Examples of magnetic force is a compass, a motor, the magnets that hold stuff on the refrigerator, train tracks, and new roller coasters. All moving charges give rise to a magnetic field and the charges that move through its regions, experience a force.
What are 5 facts about magnets?
Fun Magnet Facts for kidsOne end of a ‘bar’ magnet is a north pole and the opposite end is a South Pole.The North Pole of one magnet will repel and push away the North Pole of another magnet.The South Pole of one magnet will repel and push away the SouthPole of another magnet.More items…
What causes a magnetic force?
Magnetism is the force exerted by magnets when they attract or repel each other. Magnetism is caused by the motion of electric charges. Every substance is made up of tiny units called atoms. … Their movement generates an electric current and causes each electron to act like a microscopic magnet.
Is magnetic field a force?
Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. It is the basic force responsible for such effects as the action of electric motors and the attraction of magnets for iron.
