statements concerning permanent magnets is false? The north pole of a permanent magnets is attracted to a south pole. All permanent magnets are surrounded by a magnetic field. The direction of a magnetic field is indicated by the north pole of a compass. Magnetic field lines outside a permanent magnet originate from the north pole and end on the south pole When a permanent magnet is cut in half, one piece will be a north pole and one piece will...
T//F with concept explanations True or false: Clearly write whether the statement is true or false in the blank. Write a brief explanation for the reasoning used to arrive at your answer in the space provided, 1 point each. 1) A bar magnet is surrounded by a magnetic field. The field lines flow from the bar magnet's north pole to its south pole Answer 2) A compass needle points toward the Earth's North Pole at the Artic. The compass needle...

8.4. Quadrupole focusing. A magnetic quadrupole field can be used as a focusing field for a charged particle beam. The cross section of the pole faces is shown in Fig 8.29. The pole faces are hyperbolas of the form xy-constant. There are two north poles and two south poles, marked on the figure. The dimension of the magnet per- pendicular to the cross section is . The magnetic field in the region 0 zs is B(x, y, z)-b(vi +n) in...
Can someone please help me with D and E. Constants Part A To understand the magnetic force on a straight current-carrying wire in a uniform magnetic field. Magnetic fields exert forces on moving charged particles, whether those charges are moving independently or are confined to a current- carrying wire. The magnetic force Fon an individual moving charged particle depends on its velocity and charge er. In the case of a current-carrying wire, many charged particles are simultaneously in motion, so...
(a) Which part of an atom is positively charged, and which part is negatively charged? (b) How does the charge of an electron compare with the charge of another electron? (c) How does the charge of an electron compare with the charge of a proton? Can charge be created or destroyed? How does that answer relate to the conservation of charge? How is electric charge similar to mass? How are they different? What are two ways electric charge can be...
