What is the formula of magnetic effect?

For a wire exposed to a magnetic field,F=IlBsinθ F = IlB sin ⁡ describes the relationship between magnetic force (F), current (I), length of wire (l), magnetic field (B), and angle between field and wire (θ). The direction of the magnetic force can be determined using the right hand rule, as in fig [[17951]].

What is the rule of repulsion for magnets?

Every magnet has both a north and a south pole. When you place the north pole of one magnet near the south pole of another magnet, they are attracted to one another. When you place like poles of two magnets near each other (north to north or south to south), they will repel each other.

What is the law of magnetic attraction and repulsion?

Any object that exhibits magnetic properties is called a magnet. The law states that the force of attraction or repulsion between two magnetic poles is directly proportional to the product of the strengths of the poles and inversely proportional to the square of the distance between them.

What is attraction and repulsion property?

Attractive Property – Magnet attracts ferromagnetic materials like iron, cobalt, and nickel. Repulsive Properties – Like magnetic poles repel each other and unlike magnetic poles attract each other. Directive Property – A freely suspended magnet always points in a north-south direction.

What is attraction and repulsion?

Attraction is a force between two or more dissimilar or unlike charges. Repulsion is a force between two or more similar or like charges.

What is the formula of magnetic field class 12th?

The magnetic field formula contains the constant^{\mu_{0}}. This is known as permeability of free space and has a value^{\mu}_{0} = 4\pi \times 10^{-7} (T \cdot m/ A). Besides, the unit of a magnetic field is Tesla (T).

What is attraction and repulsion Class 6?

Repulsion occurs when like poles (N-N or S-S) of the magnets are kept closer to each other. Attraction occurs when unlike poles (N-S or S-N) of the magnets are kept closer to each other.

What is the attraction or repulsion of magnetic materials?

magnetism
The attraction or repulsion of magnetic materials is called magnetism.

What does repulsion mean in chemistry?

(noun) a force that moves two bodies away from each other.
