3/1/ 5 Examples –One component of a magnetic field has a magnitude of T and points along the +x axis, while the other component has a magnitude of T and points along the −y axis. A particle carrying a charge of x 10‐5 C is moving along the +z axis at a speed of x m/s. Circular field of magnetism- it has magnetic force lines that run around the part’s perimeter in a circumference. A circular field of magnetism is created in particles by the passage of current in a component. Importance of the direction of magnetic field. The type of field of magnetism formed is influenced by the method of magnetization used. Magnetic Sector Basics 2/12 The resultant accelerated ions are then inserted into magnetic field. If the direction of travel is perpendicular to the field, the ions follow a circular trajectory with radius r. This is because the magnetic force, F = qvB, is counterbalanced by . magnetic field strength would be required to bend these into a circular path of radius r= m? Solution: To have a circular path, the magnetic field has to be perpendicular to the velocity, i.e. Θ=90o or sinΘ=1. The magnetic force provides the centripetal acceleration: qvB=mv2/r thus B= mv2/rqv.

Geomagnetic field, magnetic field associated with Earth. It is primarily dipolar (i.e., it has two poles, the north and south magnetic poles) on Earth’s surface. Away from the surface the dipole becomes distorted. The field is variable, changing continuously, and its poles migrate over time. A magnetic field of magnitude E-3 T is measured a distance of cm from a long straight wire. What is the current through the wire? Solution: Using one can solve for I. I = amps, quite a current! Example #2. Problem: a.) Two wires carry currents in the same direction as shown below. Where are the points where the magnetic field is zero?

The magnetic eld exerts a force F~on any other moving charge or current that is present in the eld. A magnetic eld is a vector eld, B~. magnetic eld lines: a representation of the magnetic eld by vectors. The lines are drawn so that the line through any point is tangent to the magnetic- eld vector B~at that point. Magnitude of the magnetic force.

The difference between the flight times of a reference particle — moving along the optic axis of some electric or magnetic optical element — and some particle moving along an arbitrary. The Hall Effect Up: Magnetism Previous: The Lorentz Force Charged Particle in a Magnetic Field Suppose that a particle of mass moves in a circular orbit of radius with a constant is well-known, the acceleration of the particle is of magnitude, and is always directed towards the centre of the follows that the acceleration is always perpendicular to the particle's. The magnetic force is the source of the required centripetal force. qB mv r qvB r mv F F M C = = = or 2 For a given magnetic field and selected charge velocity, the radius of the circle depends on the mass of the charged particle. This is the basis for a MASS SPECTROMETER. Problem: An electron moves in a circular orbit of radius m in a. two distinct classes of objects. Some quantities, denoted scalars, are represented by real numbers. Others, denoted vectors, are represented by directed line ele-ments in space: e.g.,! PQ in see Fig. Note that line elements (and, therefore, vectors) are movable, and do not carry intrinsic position information: i.e., in Fig. ,! PS and!
