MAGNETIC FORCE (Lorentz)

MAGNETIC FORCE (Lorentz)
Of the Oersted experiment, you already know that the poles of the magnetic needle (eg compass) underwent a magnetic force generated by electric currents. Do the opposite effect on the electrical current carrying conductor in a magnetic field of magnetic force will arise? Above questions can be answered by conducting an experiment as follows:
I. Experiment Objectives Investigate the phenomenon of magnetic force acting on the electric current carrying wire in a magnetic field.
II. Tools used: 1. Circuit board 1 piece 2. Magnets U 1 piece 3. 1 piece pole switch 4. The bridge connecting 4 pieces 5. Cable Connector 1 pc 6. Plug pins have 4 pieces 7. Battery 4 pieces 8. Ampere meter 1 piece

III. Step Activity 1. Series of tools such as image


 2. The switch in the open position (position 0) 3 Ampere meter with a measuring limit of 5 A DC. 4 One connecting cable is slack stretched, mounted between the two magnetic poles N and connected to the two plug-flops. 5 Connect the circuit to a voltage source which consists of 3 pieces of battery serial (gubakan bridges) 6 Close the switch S (position 1) observe the current strength and direction of motion of the cables are in a magnetic field. 7 Open the switch S (position 0), then turn direction by reversing the battery 8 Do as step 1, and record the result into a table of observations No. 1 9 Open the switch S, then enlarge the flow by enlarging the voltage source (add a battery) 10 Do as step 1 s / d step 3 and then record the result into a table of observation No. 2
