In this Chapter we will study magnetic fields and such electromagnetic effects. We shall also study about electromagnets and electric motors which involve the magnetic effect of electric current, and electric generators which involve the electric effect of moving magnets.
Now, magnetic field lines around the secondary coil (coil-2) will change and induces the electric current in it (observed by the deflection of needle of Galvanometer in secondary circuit)
20 kwi 2024 · Magnetic Field Lines; Magnetic field lines are like invisible paths that show us where the magnetic force is strongest around a magnet. They’re kind of like the lines you see on a map that tells you where roads or rivers are.
The magnetic field lines of a magnet form continuous closed loops. The tangent to the field line at any point represents the direction of the net magnetic field at that point.
2) Magnetic field lines emerge from the north pole and re-enter at the south pole of a magnet in closed loops. 3) An electric current produces a magnetic field circulating around the conductor according to the right-hand rule. The strength of the magnetic field depends on the current.
Magnetic field lines: Magnetic field is represented by field lines. They are lines drawn in a Magnetic field along which a unit North magnetic pole moves. Magnetic field lines are called as Magnetic lines of force.
Magnetic Field: - A magnetic field is the area around a magnet where its influence can be felt by any other magnetic element. - The magnetic field is measured in Tesla or 2 Weber/m units. - Lines of Magnetic Fields - Externally, magnetic field lines exit the north pole of a magnet and enter the South Pole, forming closed loops.
