### Learn n hv Fun

Here you can watch the YouTube videos of 'Learn n hv Fun'- a YouTube channel, on various topics of physics.

1. Image formation by convex Lens
In this video watch the position and size of the image obtained for different positions of the object in front of the lens.

2. Force on a current carrying wire placed in a magnetic field

In this video you can see how a current carrying wire is deflected by a magnetic field. The direction of this force can be determine by using Fleming's Left Hand Rule.
This topic is a part of class X CBSE syllabus. This video is must for a student of class X to clear his concepts on magnetism.

Law of Inertia: The tendency of an object to resist any change in its state of rest or uniform motion along a straight line is called inertia. In other words, if an object is at rest it continues to stay at rest and if an object is in motion it continues to be in motion. To understand thÃ¨ concept on inertia, watch this beautiful video in which a child is wearing an Inertia hat.  Video courtesy : 'Learn n hv fun'- YouTube Channel (A volunteer member of the website)

5. Force on a current carrying coil and Electromagnetic induction:
Watch how a current carrying circular coil experiences a deflection in external magnetic field. The same apparatus can be redesigned for electromagnetic induction.

6. Fun with Laser, mirrors, Lens and prism
Observe how a laser is used to study reflection and refraction of light.

## 7.  Working of earth wire

The metallic body is connected to the earth wire, which provides a low resistance-conducting path for the current. It ensures that any leakage of current to the metallic body of the appliance will flow to the earth only and the user may not get a severe shock.
Watch the video below to more explanation on working of earth wire.

8. Transfer of heat through the process of convection

9.  Construction of Electric Motor
The video explains the construction of simple electric motor as per the NCERT text book class X. Students can understand how electric motor can be assembled and function.
