Solution: Since there must be some external force which will cause the deflection of charged particle and it can be both magnetic force or electric force. Perkins et al. Magnetic fields are created or produced when the electric charge/current moves within the vicinity of the magnet. Magnetism is the phenomena arising from the force caused by magnets that produce fields which attract or repel other metallic objects. At the poles of a magnet, for example, where the magnetic field is strong, the field lines are crowded together, or more dense. The electromagnetic force, also called the Lorentz force, explains how both moving and stationary charged particles interact. Magnets exert forces and torques on each other due to the rules of electromagnetism.The forces of attraction field of magnets are due to microscopic currents of electrically charged electrons orbiting nuclei and the intrinsic magnetism of fundamental particles (such as electrons) that make up the material. Magnetic field intensity is also known as the magnetizing force which is measured is ampere-turns per meter (A-t/m).
