Question: What is the relationship between current and magnetic field in a long straight conductor?

Options:

Correct Answer: Directly proportional

Solution:

The magnetic field around a long straight conductor is directly proportional to the current flowing through it.

What is the relationship between current and magnetic field in a long straight conductor?

What is the relationship between current and magnetic field in a long straight conductor?

Step 1: Understand that a long straight conductor is a wire that carries electric current.
Step 2: Know that when electric current flows through the wire, it creates a magnetic field around it.
Step 3: The strength of this magnetic field depends on the amount of current flowing through the wire.
Step 4: If the current increases, the magnetic field strength also increases.
Step 5: If the current decreases, the magnetic field strength also decreases.
Step 6: This means that the magnetic field is directly proportional to the current.
