Answer

Explanation of Magnetic Field due to a Current through a Circular Loop:
The magnetic field produced by a current flowing through a circular loop is a fundamental concept in electromagnetism. When a current passes through a wire, it generates a magnetic field around it. This magnetic field can be calculated using Ampere's law and the right-hand rule.

Formula for Magnetic Field around a Circular Loop:
- The formula to calculate the magnetic field at the center of a circular loop is given by:
$ B = \frac{\mu_0 I}{2r} $
where:
- B is the magnetic field,
- $ \mu_0 $ is the permeability of free space,
- I is the current flowing through the loop, and
- r is the radius of the loop.

Direction of Magnetic Field:
- The direction of the magnetic field can be determined using the right-hand rule. If you wrap your right-hand fingers around the loop in the direction of the current, your thumb points in the direction of the magnetic field at the center of the loop.

Properties of Magnetic Field around a Circular Loop:
- The magnetic field strength is inversely proportional to the radius of the loop. As the radius increases, the magnetic field strength decreases.
- The magnetic field is perpendicular to the plane of the loop at every point around the loop.

Applications of Magnetic Field due to a Circular Loop:
- This concept is utilized in the design of electromagnets, electric motors, and generators.
- Understanding the magnetic field around a circular loop is crucial in various engineering and physics applications.
In conclusion, the magnetic field produced by a current flowing through a circular loop plays a significant role in electromagnetism and has various practical applications in technology and science.
