Current-carrying wires produce which kind of fields?
a
frictional
b
gravitational
c
chemical
d
magnetic
The answer is (d) magnetic fields. Current-carrying wires produce a magnetic field that is perpendicular to the direction of the current flow. This is known as Ampere's law. The strength of the magnetic field produced by the current depends on the magnitude of the current and the distance from the wire.
Current-carrying wires produce magnetic fields.
The correct answer is (d) magnetic. Current-carrying wires produce magnetic fields around them. This is a fundamental principle known as Ampere's Law. To understand this, let me explain how you could arrive at this answer.
First, you need to have some knowledge of electricity and magnetism. When electric current flows through a wire, it generates a magnetic field perpendicular to the direction of the current. This principle is known as the right-hand rule, which states that if you point your thumb in the direction of the current, the curling of your fingers will indicate the direction of the magnetic field.
To verify this principle, you can perform a simple experiment. Take a straight wire and connect it to a power source to establish a current. Then, place a magnetic compass nearby. As the current passes through the wire, you will observe that the compass needle deflects from its usual orientation, aligning itself with the magnetic field generated by the current.
Keep in mind that the strength of the magnetic field depends on the current magnitude. Increasing the current will result in a stronger magnetic field. Additionally, the magnetic field strength decreases as you move further away from the wire. This is known as the principle of inverse square law.
So, in summary, current-carrying wires produce magnetic fields. This phenomenon is crucial in various applications, including electromagnets, electric motors, and transformers.
