How Is the Potential Energy of a Bobbin Calculated in a Magnetic Field?

In summary, the conversation discusses a rectangular bobbin with specific dimensions and carrying a current of 1.75 A. The bobbin is positioned at a 37º angle and is rotating on the z axis. It is inside a uniform magnetic field of 1.5T in the y-axis, with potential energy being zero at a 0º angle. The formula used to determine potential energy is dU=-muBsinthetadtheta, with mu being equal to 0.35 Am2. The final solution is -0.315 J, but the person asking for a summary would like to see the work and what the specific question is.

Homework Statement


A rectangular bobbin of 50 turns is got sides of 5.00 and 8.00 cm and carries a current of 1.75 A. I'ts orientated as shown in figure 37º and turns around z axis. Determine the potential energy of the bobbin when its inside a uniform magnetic field of 1.5T in the y-axis (potential energy is zero when angle is zero)

Homework Equations


dU=-muBsinthetadtheta
mu=NIA=0.35 Am2
B=1.5T
theta= angle between magneticfield and normal vector to the bobbin

The Attempt at a Solution

Related to How Is the Potential Energy of a Bobbin Calculated in a Magnetic Field?

1. What is a bobbin in a magnetic field?

A bobbin is a cylindrical coil of wire that is used in conjunction with a magnetic field to generate an electric current.

2. How does a bobbin create a magnetic field?

When an electric current flows through the wire of a bobbin, it creates a magnetic field around the bobbin. The strength of the magnetic field is dependent on the strength of the electric current and the number of turns in the coil of wire.

3. What is the purpose of using a bobbin in a magnetic field?

The purpose of using a bobbin in a magnetic field is to generate an electric current. This can be used in a variety of applications, such as in generators and motors.

4. How does the direction of the magnetic field affect the bobbin?

The direction of the magnetic field affects the direction of the electric current generated in the bobbin. If the magnetic field is perpendicular to the bobbin, the current will be induced in one direction. If the magnetic field is parallel to the bobbin, the current will be induced in the opposite direction.

5. Can a bobbin be used to create a continuous flow of electricity?

Yes, a bobbin can be used to create a continuous flow of electricity as long as there is a constant source of motion or energy to keep the electric current flowing through the wire. This is how generators and motors work.
