Ohms not current (amps) indicate continuity. If you have no continuity then you will read an open line condition (OL on meters). If you have continuity you will have some type of resistance reading in ohms. 0 ohms would indicate continuity 0 amps indicates no current flow.
You could have a short or it could just be that you are reading through a load. Take a lamp and check for continuity at the plug, with a bulb in the lamp you will get continuity, take the bulb out if you still have continuity then you have a short in the wire or the lamp. Same thing happens in the wiring of your house on a larger scale.
Magnetic wire has a coating of varnish for an insulation.
Where there is a red wire involved that usually indicates some type of special switching arrangement or more likely a 240 Volt circuit. In this case there will be 240 volts across the red and black and they will both be hot. Normally for 120 Volts the black is hot, the white is common and the bare wire is ground.
There isn't, unless you have a damaged switch.

Earth wire
A continuity test is performed using aids. The aids are placed across a chosen path and the flow of the current is checked.
Check the continuity of the ground wire from both the ends. Ensure the ground wire is properly connected to earth / ground terminals
1) A continuity tester is a simple device consisting of two testing probes and a light (LED) or buzzer indicator. It is used to detect the presence of continuity or a break in between the two ends of a conductor which is connected to its testing probes. For instance, if the two probes of a continuity tester are touched to the two ends of a wire bundle, its indicator may get activated to confirm that there is no interruption in the continuity of the wire and everything's fine, or, if the indicator shows no action it would mean that there's a break in the continuity of the wire and needs attention. It may also be used to trace out faults in complicated electronic.
It is electricians terminology to check the continuity of a circuit or a wire.
Magnetic wire has a coating of varnish for an insulation.
It means flow of electrons is possible through the wirei.e no cuts/breaks/no high resistance is offered by wire.
Resistance and Continuity
Get a voltmeter Set it to OHMS scale touch the two leads together--needle should run full scale indicating continuity (wires all connected) same wire indicating NO RESISTANCE If you test for continuity-you are looking for no resistance= wire continues
