To understand what exactly is a Magnetic force

To understand the behavior of the magnetic field around a current-carrying conductor

Understanding about the force acting on a current-carrying conductor kept in a magnetic field.

The student will be able to,

interpret Biot-Savart law by the relevant expression.

Derive the expression for magnetic flux density at the center of a current-carrying circular coil.

Mention the expressions for magnetic flux density outside an infinitely long straight conductor and along the axis of a long solenoid carrying currents.

Derive the expression for the force between two parallel infinitely long current carrying conductors.

Solve problems related to the magnetic flux density of current-carrying infinitely long straight conductor, circular coil and long solenoid.

Define "Ampere" 

Express the magnetic force in terms of magnetic flux density, current and length of the conductor.

Use the expression for force acting on a moving charge in a magnetic field.

Find the direction of the above magnetic force by Fleming’s left-hand rule.

The following areas will be discussed in 4 session

7.1

-Magnetic flux density

-Force acting on a charge moving in a magnetic field

-The magnitude of the force

-The direction of the force

-Hall effect

-A qualitative explanation of Halls effect

-Derivation of expression for Hall voltage

7.2

-Biot –Savart law

-Maxwell’s corkscrew rule

-Magnetic flux density near a current-carrying infinitely long straight conductor

-Magnetic flux density at the center of a current-carrying circular coil

-Magnetic flux density along the axis of a current-carrying long solenoid

-Magnetic force field

-Definition of Ampere

-Force acting on a current-carrying conductor placed in a magnetic field

-The expression for the magnitude of the Magnetic force

-Fleming's left-hand rule

-The magnitude of the force between two current-carrying infinitely long parallel conductors

7.3

-Rectangular coil placed in a uniform magnetic field

-Rectangular coil placed in a radial magnetic field

-Moving coil galvanometer

-Expression for deflection

-Factors affecting the current sensitivity

-Direct current motor

In addition to the discussion of the Theory topics, past paper questions will be discussed from 2000 A/L - 2019 A/L, and also Model MCQ and Essay questions will be discussed.

The session plan will be as follows

20th Wednesday -- 9 am to 11 am

24th Sunday -- 9 am to 11 am

27th Wednesday --  9 am to 11 am

31st Sunday -- 9 am to 11 am

 

The course is conducted by Channa Hatharasinghe who is a BSc.(Physics) special graduate from the University of Sri Jayewardenepura and currently employed as a teaching assistant in the Department of Physics at the University of Sri Jayewardenepura. Also, he was a former Summer student at CERN in 2019 and also been working as a supportive teacher at LivePhysics for more than 2 years.
