Electricity shows magnetic effecta)Trueb)FalseCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

True to check this you can take a compass near a circuit and it will deflect this proves magnetic effect of current.
deflection of compass needle proves magnetic effect of current.

Answer

Electricity shows magnetic effect by the property of magnetic effect of current using an electromagnet. Ex: bells, loudspeakers.

Answer

A because like and unlike charges repel

Answer

The Magnetic Effect of Electricity

Electricity and magnetism are closely related phenomena. When an electric current flows through a wire, it creates a magnetic field around the wire. This phenomenon is known as the magnetic effect of electricity. The magnetic effect of electricity is a fundamental principle of electromagnetism.

Explanation:
The magnetic effect of electricity can be explained by the relationship between electric currents and magnetic fields. An electric current is a flow of charged particles, usually electrons, through a conductor like a wire. When these charged particles move, they create a magnetic field around them.

The magnetic field created by an electric current can be visualized using the right-hand rule. If you point your thumb in the direction of the current flow, the curling of your fingers will indicate the direction of the magnetic field lines. The magnetic field lines form closed loops around the wire and are perpendicular to the direction of the current.

Electromagnets
The magnetic effect of electricity can be enhanced by wrapping the wire into a coil and passing a current through it. This creates an electromagnet, which can produce a stronger magnetic field. The strength of the magnetic field depends on the number of turns in the coil, the amount of current flowing through the coil, and the material of the core around which the wire is wrapped.

Electromagnets have a wide range of applications, from electric motors and generators to magnetic resonance imaging (MRI) machines. They can also be used to attract or repel magnetic materials, control the motion of objects, and convert electrical energy into mechanical energy.

Magnetic Fields and Electric Currents
The magnetic effect of electricity also explains the interaction between magnetic fields and electric currents. When a wire carrying an electric current is placed in a magnetic field, it experiences a force. This phenomenon is known as the magnetic force.

The strength and direction of the magnetic force depend on the strength and direction of the magnetic field and the current flowing through the wire. The magnetic force can cause the wire to move or exert a torque on it, depending on the orientation of the wire with respect to the magnetic field.

Conclusion
In conclusion, the statement 'Electricity shows magnetic effects' is true. When an electric current flows through a wire, it creates a magnetic field around the wire. This magnetic effect of electricity is the basis for the operation of electromagnets and the interaction between magnetic fields and electric currents.

Answer

False
Electricity shows heating effect

Answer

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. This phenomenon is called electromagnetism
