# Who Described The Magnetic Effect Of Electric Current?

The correct answer is Hans Christian Oersted. The magnetic effect of electric current was discovered by H.C. Oersted in 1820. He observed that the flow of electric current through a conductor produces a magnetic field around it.

### What is magnetic effect class 10?

Thus, the magnetic effect of electric current is defined as the electromagnetic effect. Which means that if a magnetic compass is brought near a electrically charged conductor then the needle of this compass gets deflected because of the flow of electricity.

### What are the ways to induce current?

• If a coil is moved rapidly between the two poles of a horseshoe magnet, then an electric current is induced in the coil.
• If a magnet is moved relative to a coil, an electric current is induced.
• By keeping it stationary and rotating a magnet inside it, the current in the coil can be induced.

### What induces a magnetic field?

Alternating electric current flows through the solenoid on the left, producing a changing magnetic field. This field causes, by electromagnetic induction, an electric current to flow in the wire loop on the right.

### What is the magnetic effect of current How was it discovered?

The magnetic effect of an electric current was discovered by Hans Christian Oersted in 1820. He demonstrated the effect by plotting compass close to a long straight wire which is carrying current and noting it's deflection.

### What is the formula of magnetic field B?

B = μ0I/(2πr). This equation is derived from one of Maxwell's equations called Ampere's law. The proportional constant μ0 = 4π*10-7 N/A2 is called the permeability of free space. If we imagine a circular loop of radius r, then the magnetic field is tangential to the loop.

### What is magnetic field and field lines Class 10?

A magnetic field is represented by a series of lines around a magnet. The path along which north pole moves in a magnetic field is called magnetic lines of force or magnetic field line. They show the direction and strength of magnetic field.

### On which effect of the electric current is it based?

An electric current is passing through a conductor which becomes hot after some time and produces heat. This is due to the conversion of some of the electrical energy that passes through the conductor, into heat energy. This effect of electric current is called the heating effect of current.

### What is magnetic effect class 10th?

According to magnetic effects of electric current class 10, a magnet is an object that attracts or repels other magnetic materials (such as objects made of iron, cobalt and nickel) with its magnetic field.

### What are the two main effects of electric current?

Effects of electric current are:

• Heating effect.
• Magnetic effect.

### Why does magnetic field induce current?

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.

### What is a magnetic effect of electric current?

When an electric current passes through a wire, it behaves like a magnet. This is the magnetic effect of the electric current. If the electric current does not passes through, it loses its magnetic effect. These coils of wire is called electromagnets.

### What is magnetic effects of electric current?

When an electric current passes through a wire, it behaves like a magnet. This is the magnetic effect of the electric current. If the electric current does not passes through, it loses its magnetic effect. These coils of wire is called electromagnets.

### What are the factors affecting the magnetic effect of electricity?

The four main factors that affect the strength of an electromagnet are the loop count, the current, the wire size, and the presence of an iron core.

### What is magnetic effect of electric current Class 8 Definition?

The term 'magnetic effect of electric current' means that an electric current flowing in a wire produces a magnetic field around it.

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

What Are Two Effects of Electric Current? Electric current has two effects; heating effect and magnetic effect. This happens because a magnetic field is generated around the wire as electric current passes through a conductive wire. The magnetic field causes the magnetic compass to deflection.

### Where the magnetic effect of current is used?

Magnetic effect of current is used – Electric bell, Cranes to lift magnetic material.

### What is magnetic effect of electric current class 10th?

Thus, the magnetic effect of electric current is defined as the electromagnetic effect. Which means that if a magnetic compass is brought near a electrically charged conductor then the needle of this compass gets deflected because of the flow of electricity.

### What do you mean by magnetic effect of electric current 7?

Answer: When electric current passes through the wire current carrying wire behaves like a magnet. This is called magnetic effect on current. When electric current passes through the wire current carrying wire behaves like a magnet. This is called magnetic effect on current.

### What are the 3 effects of an electric current?

The three effects of electric current are:

• Heating effect.
• Magnetic effect.
• Chemical effect.

### How can induced current be produced?

An induced current is produced by a changing magnetic field. There is an induced emf associated with the induced current. A current can be produced without a battery present in the circuit. Faraday's law of induction describes the induced emf.
