His research interests involve a broad range of theoretical physics topics, including those in quantum field theory and theoretical cosmology. According to right hand rule, if you hold the axis with your right hand and rotate the fingers in the direction of motion of the rotating body then thumb will point the direction of the angular velocity. At the time of filming his course on magnetism, he was a Professor of Physics at Lewis & Clark College in Portland, Oregon in the United States. Mohamed Anber is a Professor of Mathematical and Theoretical Particle Physics at Durham University. The sixth and final mini-lecture goes over two demonstrations, the first involving natural magnets, and the second displaying Faraday’s Law. The fifth mini-lecture introduces a useful tool called the right hand rule that allows us to determine the direction of a magnetic field due to a wire carrying current, before introducing the principle of superposition and using these two new concepts in a variety of examples involving two infinite wires carrying current. In the fourth mini-lecture we turn towards an application of magnetism, the electric generator, and work through a calculation that gives us the electromotive force (EMF) of the electric generator. The third mini-lecture introduces magnetic flux in order to understand Faraday’s Law. If the forefinger points in the direction of the field and the thumb. In the second mini-lecture we define the magnetic force and explore examples involving the magnetic force of one infinite wire on another. Extend the thumb, forefinger, and second finger of the right hand mutually at right angles. The magnetic field pointer finger is directed from North to South (that usually means from red to blue). In the first mini-lecture, we discuss the magnetic fields of natural magnets and infinite wires carrying current. Using your right hand, the current flows from positive to negative thumb. In this course, Professor Mohamed Anber (Durham University) explores magnetism. The particle is then pulled in the direction of this force (upwards).In this mini-lecture, we introduce the right hand rule and superposition, focusing in particular on: (i) how to use the right hand rule to determine the direction of the magnetic field of a wire carrying current (ii) the superposition principle, where we see that if there is more than one source of a magnetic field, then the magnetic field at some point is the sum of all the magnetic fields at that point and (iii) two examples that require the right hand rule and the superposition principle to solve.Using Fleming's left-hand rule, the first finger points into the page and the second finger (current) points to the right.For example, when a positively charged particle enters a magnetic field into the page from left to right:.Therefore, if a particle carries a negative charge, the second finger should be pointed in the opposite direction to its motion.This means that for negative charges, such as electrons, their flow will be in the opposite direction to which the second finger points. This can be found using Fleming's left-hand rule by remembering that the second finger represents the current flow or the flow of positive charge.The direction of flow of the charged particles. The direction of the magnetic force on positive and negative charged particles depends on.
