Lorentz Force and Electric Motors - YouTube. Explanation of the Lorentz force and demonstration using a linear motor.

2008-05-06 ity [1], the Lorentz force law was derived by performing a Lorentz transformation of the electromagnetic elds and the space-time coordinates from the rest frame of an electron (where only electrostatic forces act) to the laboratory system where the electron is in motion and so also subjected to magnetic forces. A similar demonstration was given by Lorentz Force Formula The following equation is used to calculate the total force acting on a particle due to a magnetic field, known as the Lorentz equation. F = q*v*B*sin (α) Where F is the force (a) Equate the Lorentz force equation and Newton’s second law of motion: F=Q(E+u×B)=ma=m du dt (1) Q, E, B, and mare given; uis the unknown velocity we want to find. First we find the cross product u×B: u× B= aˆ x aˆ y ˆa z u x u y u z 5 0 0 =5u zaˆ y − 5u yˆa z We use this together with the quantities given in (1) to get: du dt = Q m (−4aˆ y +5u zˆa The Lorentz force equation can be applied to charged particle motion through solids and gases. An example of the former is the Hall effect in a conductor as illustrated in Figure 1.4 . In steady-state, the force of equation 1.65 on an electron q e passing through this material is zero such that: circular motion due to the Lorentz force. This means that we could now equate Eq. 3 and Eq. 5 , again, using the fact that the magnitude of the electric charge of the electron is equal to the fundamental electric charge, e.

That’s a good hint about the antiderivative required for this Lorentz problem, so we have to go backwards from the cross product, and solve for the rotation: mv0 = q m (E+v×B) v = q m E+Ωv Here Ω is: q m 0 B3 −B2 Since the mass of the electron, m = 9 .1×10−31 kg and charge of an electron, |q| = e = 1.6 ×10−19 C. The velocity due to accelerating potential 200 V. Since the speed v200 > v, the electron is deflected towards direction of Lorentz force. So, in order to have null deflection, the potential, we have to supply is.

The electric field in a region of space is E = −4ây V/m and the magnetic flux density is B = 5âx. Wb/m2. Lorentz force, the force acting on moving charged particles in a magnetic field ( Figure 1), plays a crucial role in various applications ranging from electronic  The trajectory of a point charge through an electromagnetic field can be determined using this equation along with Newton's second law ( \vec{F} = m \, \ vec{a} ). Dec 19, 2010 In physics, the Lorentz force is the force on an electrically charged particle that moves through a magnetic plus an electric field.

The right-hand rule is useful to visualize how the lorentz force works. Lorentz force is applicable in cathode ray tube television. Lorentz force, the force exerted on a charged particle q moving with velocity v through an electric field E and magnetic field B. The entire electromagnetic force F on the charged particle is called the Lorentz force (after the Dutch physicist Hendrik A. Lorentz) and is given by F = qE + qv × B. This combined force law is known as the Lorentz force. 10.1.1 Units The magnetic force law we’ve given is of course in cgs units, in keeping with Purcell’s system. The magnetic force equation itself takes a slightly different form in SI units: we do not include the factor of 1/c, instead writing the force F~ = q~v ×B .~ 90 The Lorentz force is the definition of these fields, and in F it is F = q(E + v × B) while in F′ it is F′ = q(E′ + v′ × B′). A method of deriving the EM field transformations in an efficient way which also illustrates the unit of the electromagnetic field uses tensor algebra, given below.
