Fleming's Left Hand Rule
Extend the thumb, forefinger, and the middle finger of the left hand in such a way that all the three are mutually perpendicular to each another. If the forefinger points in the direction of the magnetic field and the middle finger in the direction of the current, then, the thu..
Introduction
We have seen in the previous lesson that a current carrying conductor when kept in a magnetic field experiences forces and torques. Is reverse phenomenon possible? If we rotate the coil in a magnetic field, will current flow in the coil without we passing it? The answer is yes. ..
Distinction between Electromagnetic Waves and Matter Waves
Electromagnetic waves Matter waves Electromagnetic are associated with electric and magnetic fields perpendicular to each other and to the direction of propagation of radiation Matter waves may not be associated with electric and magnetic fields Electromagn..
Electromagnetic waves
An electromagnetic wave is a disturbance, which does not require any material medium for its propagation and can travel even through vacuum. They are caused due to varying electric and magnetic fields. Radio waves and light waves are examples for electromagnetic waves. Let us now tabul..

Discovery of Radioactivity and Nature of Radiations
>Three types of radiation from recognized radioactive elements are a -particles, b -particles and g -radiation. It was realized that radioactivity of an element is independent of its physical state, its chemical environment or temperature, suggesting that it is a property of the nucleus i.e., a nuc..
Question 2
Question: If the current in a wire is flowing in the vertically downward direction and a magnetic field is applied from west to east, what is the direction of force on the wire? Answer: Applying Fleming's left-hand rule, force acting on the wire is towards sout..

Tutor helped me on every question and help me when i was confused. Thank you Tutor Vista
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
all my questions were answered in a very clear way and i learned a new math rules which i did not know this service is very helpful - mike
You are an amazing tutor. So knowlegeable and patient. Very clear in explanations, 2 thumbs up -kelly
