Example on Magnetic Force Formula
Example 1: Find magnetic force on a charged particle travelling at 5 m/s in a magnetic field of 2 T? Its field’s direction is the same as the route of the charged particle. (Given q = 40 C)
Solution:
Given:
- Charge, q = 40 C
- Velocity, v = 5 m ⁄ s
- Magnetic Field, B = 2 T
Because the second particle’s route difference is the same as the direction of its field, θ = 30°
F= q v B sin θ
F = 40 × 5 × 2 × sin 0°
F = 0
Hence, the magnetic force of charged particles is 0 N.
Example 2: Find the particle force on a charged particles travelling at (v) 20 m/s in a magnetic field of (B) 10 T? If the angle between q and B is 30° (Given q = 4 C)
Solution:
Given:
- Charge, q = 4 C
- Velocity, v = 20 m ⁄ s
- Magnetic Field, B = 10T
- θ = 30°
F= q v B sin θ
F = 4 × 20 × 10 × sin 30°
F = 400 N
Hence, the magnetic force of charged particles is 400 N.
Magnetism
Magnetism in Physics is defined as the property of the material that is responsible for the magnetic behaviour of the magnets. Magnetism is defined as the force that is produced by the moving charge and it attracts or repels other magnets and moving charge. Initially, magnetism is defined as the property of some material to attract or repel some other magnets. Later it was discovered that all the moving charges are considered to be magnets and their property of attraction or repulsion is called magnetism.
Here, in this article, we will learn about, Magnetism Definition, History of Magnets, Causes of Magnetism, Magnetic Materials, Properties of Magnets and others in detail.
