Question

3) Derive an expression for magnetic force on a arbitrarily shaped wire carrying a current.​

Answer 1

Answer:

Current I=need (i)

Magnetic force on each electron =avdBsinθ .(ii)

Volume of conductor V=AL.

Therefore, the total number of free electrons in the conductor =nail.

Using equation (i) F=IBLsinθ .(iii)

∴F=ILBsinθ

Force will be maximum when sinθ=1 or θ=90o.

Answer 2

An expression of the magnetic field on an improperly shaped wire holding a current:

• Magnetic force is the result of the electromagnetic force, which is one of the four basic forces of nature and is caused by the movement of charges.
• Two charging devices with the same motion sensors have a magnetic field between them.
• It is known as the magnetic field and forms an integral part of electromagnetism.
• The force is present between the two magnets, due to the interaction of their magnets.
• This force causes the magnets to attract or repel each other.
• The force is present between two moving particles, which are electrically charged, making them attractive or chasing each other.
• Such an expression is easily written depending on the nature of the call r = r (speak).
• We demonstrate the usefulness of our result by calculating the magnetic field in certain areas of the plane due to the waves flowing in conic curves, spirals.
• F = Il × B.
• This is the sum total of all the free moving electrons in the current-carrying conductor mounted on a magnetic field.
• Maximum capacity:
• Maximum power is F = BIl sinθ.
• If the conductor is located near the magnetic field direction,  θ = 0 ∘, then press F = 0.

• In this work, using Biot-Savart law and its natural geometric structures, we obtain a very simple expression that allows for precise magnetic field calculations due to the incorrect current power cables, in the center. the same plane as the current filament.
• Such an expression is easily written depending on the nature of the call r = r (θ) .1448
