Objective of the experiment: To study the magnetic field produced by electric current in a straight wire.

Theory: When electric current flows through a straight wire, a magnetic field is generated around it. The direction of the magnetic field around a straight wire can be determined using the right-hand rule: curl your right hand fingers around the wire, and your thumb points in the direction of current flow. The magnetic field circles around the wire in the direction your fingers curl.

Sensor position: Position the sensor as described in the experiment setup.

Procedure:

1. Follow the experimental setup as instructed.

2. Supply current to the straight wire.

3. Use the magnetic field probe at various positions around the wire, 1-10 cm away.

4. Plot a graph showing the relationship between distance and magnetic field value.
