In fact the earth has a north and south pole that is magnetized, which creates a magnetic field around the earth. 2:21 Also, option (A) and (B) are saying that there should be electric field compulsory or magnetic field compulsory for a deflection which is not true, therefore, the only option is (C).What about 2 m magnetic feild?

Did you know if you rub a magnet on some objects, that item can become magnetized for a short amount of time?

Even in earlier experiments with electricity, scientists realized that electricity and magnets have a lot in common.
Electrons travel around atoms, and usually they go around the atom in circles paired together with another electron.

Magnetic poles Every magnet has two poles , north and south. A) There must be an electric field B) There must be a magnetic field.
In fact, the number of lines relates to the magnetic field’s strength at a given point.
This area affected from the force of magnets called magnetic field.

Fleming’s Left-Hand Rule predicts the direction of the magnetic forces,where F is the magnetic force, I is current, l is the length of a straight conductor in a uniform magnetic field B and θ is the angle between I and B.Question: If a charged particle projected in a gravity-free room deflects, thenA) There must be an electric field B) There must be a magnetic field.C) Both fields cannot be zero D) None of theseSolution: Since there must be some external force which will cause the deflection of charged particle and it can be both magnetic force or electric force.
3:14 That's why when you rub a magnet on iron, it can become magnetized!
Explanation of Electromagnetism with an Example.
They hv not asked at centre!!!!!
Paramagnetic materials examples. What r examples of magnetic force?
Search. Just like if you put two magnets together you'll create a bigger, stronger magnet, this also happens at an atomic level.
This magnetic field can be seen when you put a magnet close to something magnetic and it starts to move.
6 7 8. paramagnetic substances are those which are attracted by magnets and when placed in a magnetic filed move from weaker to stronger parts of the field.
Solved Examples For You.
Atoms are the tiny building blocks for everything on earth and are made up of three parts: protons, neutrons and electrons.
Learn what magnetic force is and how to calculate it. 4:24
Refrigerator magnets – artwork & messages : A refrigerator magnet is a hard object, and more specifically a permanent magnet.

This field can go through materials like wood and cloth, and even thicker material depending on the strength of a magnet.

We cannot see magnetic field necked eye.

Furthermore, the tangent of any A current-carrying conductor experiences magnetic forces in a magnetic field.

Magnets exert forces and torques on each other due to the rules of electromagnetism.The forces of attraction field of magnets are due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of fundamental particles (such as electrons) that make up the material.
Magnetic Force can be defined as the attractive or repulsive force that is exerted between the poles of a magnet and electrically charged moving particles. Connect with a tutor instantly and get your

Therefore, simultaneously both the fields cannot be zero, therefore, option (C) is the answer.
But really magnets are just objects that have north and south Did you know… We have over 200 college
For example, if current i.e., positive charges moving in a wire, it produces the magnetic field along the wire, and the direction of magnetic lines and force can be determined using Right-hand Rule.
