• Pole = the two o_pposite regions in a m_agnet, where the magnetic field is c_oncentrated, can be north or s_outh
• Permanent magnet = an object that p_roduces its OWN m_agnetic field
• Induced magnet = an object that BECOMES m_agnetic when placed in a m_agnetic field
• Solenoid = a c_oil of w_ire partially surrounding an iron c_ore, which is made to move i_nside the coil by the magnetic f_ield set up by a c_urrent; used to convert e_lectrical to m_echanical energy.
• Uniform = unchanging in form, quality or q_uantity; r_egular
• Electromagnet = a m_agnet consisting of an iron or s_teel core wound with a c_oil of wire, through which a c_urrent is passed.
• Motor effect = the f_orce experienced by a current carrying c_onductor when it is placed in a m_agnetic field, which is used to create m_ovement in electrical m_otors
• Flux density = a measure of the d_ensity of the field l_ines around a m_agnet
• Commutator = a device used to r_everse the direction of f_low of an electric c_urrent in motors and g_enerators
