How can we find the direction of magnetic field induced due to electric current?

How can we find the direction of magnetic field induced due to electric current?

A current traveling through a loop of wire creates a magnetic field along the axis of the loop. The direction of the field inside the loop can be found by curling the fingers of the right hand in the direction of the current through the loop; the thumb then points in the direction of the magnetic field.

Does AC current show magnetic field?

An alternating current does not show any magnetic effect.

What happens to the magnetic fields in AC?

If you connect an A.C. source the magnetic field alternates in polarity. It is interesting to note that a magnetic field is only measured or observed when a charge moves relative to you as an observer. It is a relative property!

Why the direction of magnetic field is from north to south?

So the direction of field lines is determined by the direction of force. So in case of magnet consider a bar magnet having two poles , a north and a south . Opposite poles attract. So north poles seeks south pole and south pole seeks north pole .

How should the direction of the magnetic field at every point?

Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the north pole of the magnet, toward the south pole of the magnet.

Does AC show chemical effect?

Answer: In both battery charging and electrolysis, an electric field applied across the electrolytic solution or paste causes a chemical change. Applying AC would be charging the battery in one half of the cycle, and discharging it in the other half – the net effect is zero.

Does magnetic field have direction?

they are produced only by moving charges while electric fields are produced by both moving charges and stationary charges. moving charge is perpendicular to the direction of motion. The direction of the force due to a magnetic field is perpendicular to the direction of motion.

What happens when a conductor passes through a magnetic field?

Current is produced in a conductor when it is moved through a magnetic field because the magnetic lines of force are applying a force on the free electrons in the conductor and causing them to move. This is called induction because there is no physical connection between the conductor and the magnet. …

How would you reverse the direction of the current flowing through coil in Faraday’s experiment?

How would you reverse the direction of the current flowing through the coil in Faraday’s experiment? The coil generates a stronger magnetic field.
