Important Topics for HC Verma Concepts of Physics Part-2 Solutions Chapter 35: Magnetic Field Due to Current

Biot-Savart Law

The Biot-Savart law is defined as an equation where the magnetic field is created by a constant electric current. It relates the magnetic field to the direction, length, magnitude, and proximity of the electric current.

Magnetic Field Due to Current Passing through a Straight Wire

The concentric circles whose centres lie on the wire are the magnetic field lines over a straight conductor carrying current. Using Right-Hand Thumb Rule the direction of magnetic field lines can be determined.

Field due to Circular Current

The magnetic field over a  straight conductor carrying current can be increased by warping the wire into a circular loop. With the help of a large number of small straight wires, a circular loop is made. A magnetic field is made by an electric current flow over a circular coil of wire. 

Ampere’s Law

Ampere’s law defines that the magnetic field made by an electric current is directly proportional to the size of that electric current with a constant or proportionality equivalent to the accessibility of free space. Stationary charges generate an electric field directly proportional to the magnitude of the charge.

Solenoid

A solenoid refers to a type of electromagnet producing a controlled magnetic field over a coil wound into a  tightly packed helix. The coil can be in an order to generate a uniform magnetic field in a volume of space when an electric current is passed over it.

Toroid

A toroid is defined as a coil which is an insulated wire wound on a doughnut-shaped type formed by powdered iron. In electronic circuits, a toroid is used as an insulator, mainly at low frequencies where large inductances are essential.

Magnetic Field Produced at a Point due to Long Straight Current

 The magnetic field produced by current:

  • Compasses placed nearby a straight carrying current wire specifies that filed lines form circular loops centred on the wire.
  • Right- hand rule 2 defines that if the right- hand thumb point is in the direction of the current then the fingers bend in the direction of the field.
