how to get a rheostats to create heat? project?

i want to heat a piece of metal up ( copper ) with a rhetostat. this is all home made with a small extension cord,120 v light dimmer. im using a thin metal to try and heat it up. is 120 v enough to heat it up or not enough? i figure no but cannot find out. and im using lots of safety percautions doing this .
i meant i know 120 v is enough but unsure. but i am not sure what you mean by issue is heat current. the powers there but there isnt enough current to get it there? well how can i a improve this? more metal? thicker wires? thinner wires?

This is a very dangerous experiment to heat up copper wire with 120V. And no body uses copper wire as heater. The dimmer blows right away because of overload.
You need Nickle chromium heater wire and the total resistance at least 30 ohm. Dimmer cannot handle more than 600 watts power.

hi,im doin a project on an RC car but i dont kno how to find speed and/or torque.can anyone help please?

hi, my name is Jolene, 20, studing aerospace, im using the RC car to create an electromagnetic braking system. i’ve replaced one of the wheels with a metal disc, and 2 electromagnets on either side attached to an aluminium frame( like this ]- | -[ where the brackets are the aluminium frame, line int he middle is the disc and the minus signs are the magnets). it doesn’t seem to work. the feild produced is way too small.i connected one of the solenoid to a car battery but it only seemed to heat. if anyone has any ideas on wat i can do to make the FIELD produced by the electromagnets to stop the disc from rotating please help. if u can, suggest any formulas and other requirements (i.e. weight of the disk, speed of rotation,etc) to make this work.

That sounds quite tricky, the best way to make a brake for an RC car is not electromagnetics but when the brake is applied, short circuit the motor, the current inducted in the motor tries to force it back the other way, slowing it down, this is how electronic speed controllers work, they do it proportionally to stick position though.

I’d try using a steel disc as opposed to ally, being ferrous, it might work a bit better?
