Answer 1

F=I*B*L=4*0,88*0,3=1,056 H

Answer 2

Calculating the Force on a Conductor in a Magnetic Field

To calculate the force acting on a conductor with a current of 4 A and a length of 30 cm placed in a magnetic field with an induction of 0.88 T, we can use the formula for the magnetic force on a current-carrying conductor in a magnetic field.

The formula for the magnetic force on a current-carrying conductor in a magnetic field is given by:

F = BIL*sin(θ)

Where: - F is the magnetic force (in newtons, N) - B is the magnetic field induction (in teslas, T) - I is the current (in amperes, A) - L is the length of the conductor (in meters, m) - θ is the angle between the direction of the current and the magnetic field

Applying the Formula

Using the given values: - I = 4 A - L = 30 cm = 0.3 m - B = 0.88 T

We can calculate the force acting on the conductor.

F = (0.88 T) * (4 A) * (0.3 m) * sin(θ)

As the angle (θ) between the direction of the current and the magnetic field is not provided, we'll assume a right angle (90 degrees) for simplicity.

Calculating the Force

Substituting the given values into the formula: F = (0.88 T) * (4 A) * (0.3 m) * sin(90°)

The sine of 90 degrees is 1, so the force can be calculated as: F = 0.88 * 4 * 0.3 * 1 = 1.056 N

Therefore, the force acting on the conductor in the magnetic field with the given parameters is approximately 1.056 N.
