1. An electron moving straight down (into the page) at a speed of 4.82 x 10' m/s experiences a force of 3.07 x 10-12 N directly east. What magnitude of the magnetic field? (The charge of an electron is -1.6 x 10-19 C) 1.48 x 10-4 T 3.26 T 0.39 T 0. 148 T2. A proton moving east at 1.30 x 105 m/s moves through a magnetic field of 4.98 x 10" T to the north. What is the magnitude of the force that the proton experiences? (charge of a proton is +1.6 x 10-19 C) 1.04 x 10-18 N 4.05 x 10-18 N 1.04 x 10-12 N 4.05 x 10-12 N3. Which of the following are true? Check all that apply. It the two currentcarrying wires are placed parallel to one another and the current is moving in the same direction, the force between them will be attractive. It you place a currentcarrying wire in a magnetic field, the wire will experience a magnetic force produced by that magnetic field. It the two currentcarrying wires are placed parallel to one another and the current is moving in opposite directions. the force between them will be attractive. A current-carrying wire produces a magnetic eld around it that moves in a direction given bythe right-hand rule for a current-carrying conductor. 4. A charged particle moves in a circle in a magnetic field. What must be true about that particle? the charged particle is moving outside of a magnetic field the charged particle is moving perpendicularly to a magnetic field the charged particle is moving parallel to the magnetic field the charged particle is moving at an angle to the magnetic field5. A proton moves with an unknown velocity through a magnetic field of 3.45 x 10- T that points directly north. The proton experiences a force of 2.40 x 10-15 N directly east. What direction is the proton moving? into the page west south out of the page6. A current-carrying wire placed in a magnetic field will be deflected by a force that is proportional to: (check all that apply) the type of wire moving in the magnetic field the strength of the magnetic field the length of wire in the magnetic field the current flowing through the wire7. A proton moves with an unknown velocity through a magnetic field of 3.45 x 10- T that points directly north. The proton experiences a force of 2.40 x 10-15 N directly east. What is the magnitude of the velocity? (charge of a proton is +1.6 x 10-19 C) 6.35 x 108 m/s 4.35 x 10' m/s 4.35 x 106 m/s 8.85 x 106 m/s8.

ON 7.50 x 10-19 N 8.62 x 10-20 N 7.68 x 10-18 N9. What was Andre-Marie Ampere known for? the compass circuitry electromagnetic induction electrodynamics10. An electron moving straight down (into the page) at a speed of 2.75 x 10' m/s experiences a force of 6.07 x 10-12 N directly east. What direction is the magnetic field pointing? out of the page south north west
