Which of the following is correct about electric field and magnetic field?

Which is correct about electric field and magnetic field?

An object with a moving charge always has both magnetic and electric fields.

Difference Between Electric Field And Magnetic Field.

Difference Between Electric Field vs Magnetic Field
Electric Field Magnetic Field
Proportional for the electric charge Proportional to the speed of electric charge
Are perpendicular to the magnetic field Are perpendicular to the electric field

What is the relationship between a magnetic field and an electric field?

Key Takeaways: Electricity and Magnetism

Together, they form electromagnetism. A moving electric charge generates a magnetic field. A magnetic field induces electric charge movement, producing an electric current. In an electromagnetic wave, the electric field and magnetic field are perpendicular to one another.

Which of the following statement is correct regarding the electric field produced by a changing magnetic field?

This means that the electric field produced by a changing magnetic field due to motion of an electric charge is non-electrostatic in nature. … The induced electric field lines produced due to changing magnetic field because of the motion of an electric charge form closed curves. Thus option (D) is also correct.

What is the basic difference between electric field and magnetic field?

A magnetic field is a field explaining the magnetic influence on an object in space. A electric field is a field defined by the magnitude of the electric force at any given point in space. Current is the rate of charge moving past a region.

Is electric field and electric field intensity same?

The electric field is a vector, a quantity that has both a magnitude and a direction. The electric field intensity is the magnitude of the vector.

How are electric and magnetic fields related quizlet?

How are electricity and magnetism related? Electric current produces a magnetic field. Electric currents and magnets exert force on each other, and this relationship has many uses. A temporary magnet, known as an electromagnet, can be made by passing electric current through a wire that is coiled around an iron core.

How do electric and magnetic fields interact in an electromagnetic wave?

The electric field in an electromagnetic wave vibrates with its vectorial force growing stronger and then weaker, pointing in one direction, and then in the other direction, alternating in a sinusoidal pattern (Figure 1). At the same frequency, the magnetic field oscillates perpendicular to the electric field.

What is the difference between the magnetic field and the magnetic force of a magnet?

Therefore magnetic force is defined as, “The force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.” The space or the region around a magnet within which magnetic force is exerted on other magnet is called the magnetic field.

Which of the following statements is correct the electric field at a point is?

Electric field at a point is continuous if there is no charge at that point. And the field is discontinuous if there is charge at that point. So both options (b) and (c) are correct.

Which of the following statement is correct about electric current?

Answer: (c) Electric current has both magnitude and direction but it does not follow the vector laws of addition. Therefore, it is scaler quantity.

Which of the following statements is true about magnetic field intensity *?

Which of the following statements is true about magnetic field intensity? … Magnetic field intensity is the number of lines of force crossing per unit area. Magnetic field intensity is the magnetic induction force acting on a unit magnetic pole. Magnetic field intensity is the magnetic moment per unit volume.

In what ways are electric and magnetic fields similar and in what ways are they different?

Similarities between magnetic fields and electric fields: Electric fields are produced by two kinds of charges, positive and negative. Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges).

What is electric field and electric field lines?

An electric field line is an imaginary line or curve drawn through a region of empty space so that its tangent at any point is in the direction of the electric field vector at that point. The relative closeness of the lines at some place gives an idea about the intensity of electric field at that point.

What is the difference between electric field and electric potential?

The electric field is a measure of force per unit charge; the electric potential is a measure of energy per unit charge. … Potential is a property of the field that describes the action of the field upon an object.
