## What is the magnetic effect of a current?

The magnetic effect of electric current is known as electromagnetic effect. It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect.

What is the example of magnetic effect of electric current?

Appliances like the electric bulb, fan, television, refrigerator, washing machine, motor, radio, everything works due to electricity. When electric current passes through current carrying conductor or coil then a magnetic field is produced around it.

### Who has given magnetic effect of electric current?

Complete Step by step solution The magnetic effect of electric current was discovered by Danish Physicist, Hans Christian ørsted (Oersted) in the year 1820. One particular day in April 1820, during a lecture, he observed that the magnetic needle in the compass kept near a current-carrying wire was deflected.

What is magnetic field of electric current?

Magnetic Effect of Electric Current – A magnetic field is a force field that is created by magnetic dipoles and moving electric charges, and it exerts a force on other nearby moving charges and magnetic dipoles.

## How can we check the magnetic effect of current?

If a current carrying conductor is held by right hand; keeping the thumb straight and if the direction of electric current is in the direction of thumb, then the direction of folding of other fingers will show the direction of magnetic field.

Is Dynamo example of magnetic effect of current?

The dynamo effect is a geophysical theory that explains the origin of the Earth’s main magnetic field in terms of a self-exciting (or self-sustaining) dynamo. The electric current, in turn, produces a magnetic field that also interacts with the fluid motion to create a secondary magnetic field.

### What are the four effects of electric current?

Name four different effects of electric current?

• Magnetic effect.
• Chemical effect.
• Heating effect.
• Electric shocks.

How is magnetic effect of current checked?

Answer: If the current is flowing in an electric circuit from South to North direction and a magnetic compass is placed over the conducting wire, the needle of the compass deflects in the direction of west. This is known as SNOW rule which helps to predict the direction of magnetic field.

## What are the 5 effects of electric current?

The main effects are heating, chemical and magnetic effects. When current flows in a circuit it exhibits various effects. The main effects are heating, chemical and magnetic effects.

What are the magnetic effects of electric current?

Magnetic Effects of Electric Current 2. Magnets A substance which attracts small pieces of iron and points in North-South direction when suspended freely in known as Magnet. A naturally occurring iron ore which is called loadstone or magnetite also behaves as a magnet but it is a very weak magnet.

### How is the force of attraction around a magnet detected?

The region around a magnet where the force of attraction or repulsion can be detected is called magnetic field. Magnetic field around a magnet can be detected by using a magnetic compass. Magnetic field lines are the paths around a magnet along which the north pole of a magnetic compass needle tends to move.

How are magnetic field lines related to current?

Magnetic field due to current in a circularloopProperties of magnetic field lines1. The magnetic field lines are nearcircular at the points where thecurrent enters or leaves the card board2. Within the space enclosed by the coil,the field lines are in same direction.3.

## How are electricity and magnetism related to each other?

The electricity and magnetism are linked to each other and it is proved when the electric current passes through the copper wire, it produces a magnetic effect. The electromagnetic effects first time noticed by Hans Christian Oersted. Magnetic field is a quantity, which has both magnitude and direction.

What is the magnetic effect of a current? The magnetic effect of electric current is known as electromagnetic effect. It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect. What is…
