Correct statement and explanation:

Statement (c) is correct.

Explanation:

Surface integral of the magnetic field for any closed surface is equal to Ho times of total algebraic sum of current which are crossing through the closed surface. This statement is known as Ampere's circuital law. It is one of the four Maxwell's equations that describe the behavior of the electric and magnetic fields.

Option (a) is incorrect because the electric field is non-zero on the surface of a current carrying wire. This is because the charges in the wire produce an electric field that extends beyond the surface of the wire.

Option (b) is incorrect because the electric field is zero on the axis of a hollow current carrying wire. This is because the charges in the wire are distributed uniformly around the circumference of the wire, so the electric field cancels out along the axis.

Option (c) is correct because Ampere's circuital law is a fundamental law of electromagnetism that relates the magnetic field to the current flowing through a closed loop. The law states that the integral of the magnetic field around a closed loop is proportional to the current flowing through the loop. This law is used to calculate the magnetic field produced by current-carrying wires and other devices.

Option (d) is incorrect because only option (c) is correct.

Similar Class 12 Doubts

Read the following text and answer the following questions on the basis of the same: Earth’s magnetism: Earth’s magnetic field is caused by a dynamo effect. The effect works in the same way as a dynamo light on a bicycle. Magnets in the dynamo start spinning when the bicycle is pedaled, creating an electric current. The electricity is then used to turn on the light. This process also works in reverse. If you have a rotating electric current, it will create a magnetic field. On Earth, flowing liquid metal in the outer core of the planet generates electric currents. The rotation of Earth on its axis causes these electric currents to form a magnetic field which extends around the planet. The average magnetic field strength in the Earth's outer core was measured to be 25 Gauss, 50 times stronger than the magnetic field at the surface. The magnetic field is extremely important for sustaining life on Earth. Without it, we would be exposed to high amounts of radiation from the Sun and our atmosphere would be free to leak into space. This is likely what happened to the atmosphere on Mars. As Mars doesn’t have flowing liquid metal in its core, it doesn’t produce the same dynamo effect. This left the planet with a very weak magnetic field, allowing for its atmosphere to be stripped away by solar winds, leaving it uninhabitable. Based upon the study of lava flows throughout the world, it has been proposed that the Earth's magnetic field reverses at an average interval of approximately 300,000 years. However, the last such event occurred some 780,000 years ago.Which of the following statements is true?
