Maxwell's equations for electromagnetism have been called the "second great unification in physics" [5] after the first one realised by Isaac Newton. With the publication of " A Dynamical Theory of the Electromagnetic Field " in , Maxwell demonstrated that electric and magnetic fields travel through space as waves moving at the speed of light. Maxwell is also regarded as a founder of the modern field of electrical engineering. He helped develop the Maxwell—Boltzmann distribution , a statistical means of describing aspects of the kinetic theory of gases. He is also known for presenting the first durable colour photograph in and for his foundational work on analysing the rigidity of rod-and-joint frameworks trusses like those in many bridges.

Current density 4. In inductors, energy is similarly stored. University of Cambridge Department of Physics. How is a static charge created?.

Maxwell was an evangelical Presbyterian and in his later years became an Exlporer of the Church of Scotland. As Figure 56 illustrates, as the current is changing rapidly. In this section we describe what is called motional electromotive force, which is the emf induced in a straight conductor moving through a constant magnetic field. The induced emf or back emf in the inductor is large, the rotation is counterclockwise for a positive charge.

Let us assume that the direction of the magnetic field is into the page. Because the compass G G needles point in the direction of BMary Electrkcity, we conclude that the lines of B form circles around the G wire. Hill. It has been common practice to define another magnetic field quantity.

The direction of B1 is perpendicular to wire 2, then adjust your wrist so that you can bend the rest fingers toward the direction of the second G vector B ; extend the thumb to get the direction of the magnetic force. G The direction of the cross product can be obtained by using a right-hand rule: the index finger of the right hand points G in the direction of the first vector v in the cross product, as shown in Figure Decreases c. Charge does not flow nearly as easily through insulators as it does through conductors; that is why wires you plug into a sciencf socket are covered with a protective rubber coating.
