Conductor Field Magnetic Magnetic field Outside

In summary, a magnetic field is a region in space where a magnetic force is exerted on charged particles or magnetic materials. This force is caused by the movement of electric charges. When an electric current flows through a conductor, it creates a circular magnetic field around the conductor. The direction of the magnetic field outside a conductor depends on the direction of the current flowing through the conductor and the shape of the conductor can affect the strength and direction of the magnetic field. The strength of the magnetic field outside a conductor can be changed by altering the current, changing the distance between the conductor and magnetic material, and other factors such as the shape and material of the conductor.

Why is the magnetic field outside a conductor zero?

nonequilibrium

Where did you read that it is such?

A copper wire with a current going through it is a conductor, but surely generates a magnetic field.

Maybe you mean a conductor in equilibrium, but still... An iron magnet is a conductor.

Q: What is a magnetic field?

A: A magnetic field is a region in space where a magnetic force is exerted on charged particles or magnetic materials. This force is caused by the movement of electric charges.

Q: How does a conductor create a magnetic field?

A: When an electric current flows through a conductor, it creates a circular magnetic field around the conductor. The strength of the magnetic field is directly proportional to the amount of current flowing through the conductor.

Q: What is the direction of the magnetic field outside a conductor?

A: The direction of the magnetic field outside a conductor depends on the direction of the current flowing through the conductor. Using the right-hand rule, the direction of the magnetic field is perpendicular to the direction of the current and forms concentric circles around the conductor.

Q: How does the shape of the conductor affect the magnetic field?

A: The shape of the conductor can affect the magnetic field in several ways. For example, a straight conductor will have a uniform magnetic field around it, while a looped conductor will have a stronger magnetic field at the center. Additionally, the closer the magnetic material is to the conductor, the stronger the magnetic field will be.

Q: Can the strength of the magnetic field be changed outside a conductor?

A: Yes, the strength of the magnetic field outside a conductor can be changed by altering the current flowing through the conductor or by changing the distance between the conductor and the magnetic material. Additionally, other factors such as the shape and material of the conductor can also affect the strength of the magnetic field.
