KCET Magnetism and Matter Topics 2025: Important Formulas

Candidates who are preparing for the KCET 2025 exam must check the important formula related to the KCET Magnetism and Matter 2025 below. The formulas will help candidates get hold of the topics and solve the numerical problems easily.

Magnitude of Field at a P Point due to Solenoid 

Dipole in Uniform Magnetic Field

Equatorial Field of a Bar Magnet at Distance r

KCET Magnetism and Matter 2025: Important Definitions

For the ease of candidates we have provided the important definitions of the topics from the KCET Magnetism and Matter Topics 2025 below:

Gauss’s law for Magnetism

Gauss’s law of Magnetism states that the magnetic flux (B) across any closed surface is zero, that is div B=0 (where div is Divergence) 

Magnetic Dipole Moment

Magnets have two poles i.e. North (N) and South (S) separated by some length which creates a magnetic dipole. The moment created by the dipoles is known as the magnetic dipole moment which is measured by the formula 

m= qm x 2l 

Where, 

• m= Magnetic dipole moment 
• qm = Magnitude of the charge 
• 2l= Distance between the poles

SI Unit: Ampere Metre Squares (Am^2)

Other Unit: Joules per Tesla (J/T)

Diamagnetism

Diamagnetism is defined as the repulsive force between two materials due to the creation of an induced magnetic field by the magnetic field in them in the opposite direction

Ferromagnetism 

Ferromagnetism is a property of certain materials (such as iron) that results in a significant, observable magnetic permeability, and in many cases, a significant magnetic coercivity, allowing the material to form a permanent magnet

Paramagnetism

Paramagnetism is a form of magnetism where material is weakly attracted by an externally applied magnetic field. It creates an internally induced magnetic field in the direction of the applied magnetic field. 

KCET Magnetism and Matter Topics 2025: Previous Year Questions 

Candidates can check the previous year's questions from the KCET Magnetism & Matter topics below.

1. Moves in the direction of the field 
2. Moves in the opposite direction of the magnetic field
3. Remains Stationary
4. Starts Spinning 

Q: A toroid with thick windings of N turns has inner and outer radii R1 and R2 respectively. If it carries certain steady current I, the variation of magnetic field due to the toroid with radial distance is correctly graphed in:
