## FAQs on HC Verma Solutions Class 12 Chapter 35 - Magnetic Field due to a Current

1. How do you determine the magnetic field direction caused by a current-carrying conductor?

A magnetic field is created around a straight current-carrying conductor when electricity is transmitted through it. Every point of the current-carrying conductor has field lines in the shape of concentric circles. The Maxwell Corkscrew Rule, also known as the Right-Hand Thumb Rule, can be used to indicate the direction of the magnetic field about the flow of electric current via a straight conductor.

This rule asserts that if a current-carrying conductor is held in the right hand with the thumb straight and the electric current is flowing in the same direction as the thumb, the direction of wrapping of the remaining fingers will reveal the magnetic field's direction.

2. What is a solenoid, exactly? What is a magnetic field in a solenoid caused by a current?

The solenoid is a coil made up of numerous circular turns of insulated copper wire wrapped tightly in a cylinder shape. A current-carrying solenoid produces a magnetic field pattern that is similar to that of a bar magnet. The North Pole is represented by one end of the solenoid, while the South Pole is represented by the other.

Inside the solenoid, magnetic field lines are parallel, similar to a bar magnet, indicating that the magnetic field is the same at all points inside the solenoid. A solenoid's magnetic field is similar to that of a bar magnet. The magnetic field's strength is related to the number of turns and current magnitude.

Magnetic materials can be magnetised by creating a high magnetic field inside the solenoid. An electromagnet is a magnet created by creating a magnetic field inside a solenoid.

3. What is the right-hand thumb rule?

The right-hand rule is a hand mnemonic used by physicists to recall the direction of magnetic forces. Make an L-shape with your right hand's thumb and first two fingers to construct the mnemonic. Then, with your middle finger perpendicular to your thumb and index finger, make a "V" with your thumb and index finger.

The right-hand rule isn't based on the fundamental physics of magnetic fields and the pressures they exert on moving charges; it's only a convenient way for physicists to remember which way objects should point. Occasionally, a physicist will use their left hand inadvertently, prompting them to anticipate that the magnetic force will point in the opposite way than it does!

4. What are moving charges?

As charges remain immobile, magnetic fields do not affect them; nevertheless, when they begin to move, the magnetic field pulls against them. However, the magnetic field lines and the direction in which the field pushes on charges are not the same.

Your thumb points in the direction of the magnetic force pushing on the moving charge if you point your pointer finger in the direction of the positive charge and then point your middle finger in the magnetic field's direction. Moving electrons, for example, have a force that points in the opposite direction as your thumb.
