This is another continuation of the Partial Notes on Radiologic Physics 2. NATURE OF MAGNETISM Magnetite a magnetic oxide of iron, a rod- like stone when suspended by the string it rotates back and forth are naturally occurring magnets and were first use as compass of the ancient Chinese. Magnetism- a fundamental property of some forms of matter Any charge of particle in motion creates a magnetic field. The magnetic field of a charged particle is perpendicular to the motion of that particle. The lines of a magnetic field is always a closed- loops. Bipolar – means two poles: the Click Here To Read More

This is the continuation of the Partial Notes on Radiologic Physics 2. ELECTRIC CIRCUITS It results when the resistance is controlled and the conductor is made into closed path. TWO BASIC KINDS OF ELECTRIC CIRCUIT Series Circuit- all circuit elements are connected in a line along the same conductor – Parallel Circuit- contains elements that are connected at their ends rather than lies in a line along conductor. Ohm’s Law relationship in which describes the manner in which electric current behaves in an electric circuit. V= IR where; V= voltage I= current R= resistance Voltage- the product of resistance and Click Here To Read More

ELECTRICITY AND MAGNETISM Matter has mass and energy equivalence and may also have electric charges Electrically neutral which means, in the entire universe the total number of positive charge is equal to the total number of negative charge. Electrification derived from the word electricity Can be created by contact, friction and induction Due to the movement of negative electric charges. • The primary function of x-ray tube is to convert electric energy to EMR or x-rays. Two Studies of Electric Charges Electrostatics- the study of electric charges in stationary form. Electrodynamics- the study of electric charges in motion. Four Fundamental Click Here To Read More
