Question

magnetic induction is measured in​

Answer 1

Answer:

Magnetic Induction is measured in Tesla (T) or microtesla ( T)

Explanation:

Magnetic Induction:

• It was also known as electromagnetic induction.
• While changing the magnetic field, the electromotive force was produced across the electrical conductor.
• The discovery of induction was done by Faraday. It was mathematically described as Faraday's law of induction by James Clerk Maxwell.
• According to Faraday's law "In a closed circuit the induced electromotive force is equal to the rate of change of magnetic flux induced in the circuit"
• Magnetic induction application was electrical components like inductors and transformers which was used in generators and electric motors.

Formula:

∈ = dФ$_{b}$/dt

Where,

• ∈ = induced Electro Motive Force
• t = time
• Ф$_{b}$ = magnetic flux

If the conductor was in moving state, the Electro Motive Force was given as:

∈ = B l v sinθ

• l = length of the conductor
• v = velocity of the conductor
• θ = angle between the magnetic field and the direction of motion.

Answer 2

Answer:

The magnetic induction is measured in Tesla (wb/m⁻²).

Explanation:

• Magnetic or electromagnetic induction is the process of generating an electromotive force across an electrical conductor when a magnetic field is changing.
• According to Faraday's law of electromagnetic induction, the magnetic induction is mathematically represented as:

           ε = −dϕ/dt

where, ϕ is the magnetic flux, ϕ = B.A cosθ

and ε is the induced emf.

• The negative sign comes from Lenz's law, which states that electromagnetic induction occurs as a result of the conductor's opposition to a change in state in the potential.
• Magnetic induction is a vector quanity and is measured in Tesla (wb/m⁻²)
