Question: If the current in a wire is doubled, how does the magnetic field at a point near the wire change according to Ampere\'s Law?

Options:

Correct Answer: It doubles

Solution:

According to Ampere\'s Law, the magnetic field is directly proportional to the current, so doubling the current will double the magnetic field.

If the current in a wire is doubled, how does the magnetic field at a point near the wire change according to Ampere's Law?

If the current in a wire is doubled, how does the magnetic field at a point near the wire change according to Ampere's Law?

Step 1: Understand that a wire carrying electric current creates a magnetic field around it.
Step 2: Know that Ampere's Law states that the strength of the magnetic field is directly related to the amount of current flowing through the wire.
Step 3: If the current in the wire is doubled, it means there is now twice as much current flowing.
Step 4: Since the magnetic field is directly proportional to the current, doubling the current will also double the strength of the magnetic field.
Step 5: Therefore, the magnetic field at a point near the wire will increase to twice its original strength.

Ampere's Law – Ampere's Law states that the magnetic field around a conductor is directly proportional to the electric current flowing through it.
Magnetic Field Strength – The strength of the magnetic field generated by a current-carrying wire increases linearly with the increase in current.
