AI Thread Summary
To enhance the power of a small homemade electromagnet, focus on optimizing the wire gauge and the number of turns in the coil. Using a 0.125mm insulated copper wire is a good start, but increasing the number of turns can significantly boost the magnetic field strength. It's essential to balance the voltage and current to avoid overheating; calculations involving the core material's permeability and the desired force can guide this process. Additionally, ensuring proper insulation and heat dissipation will help maintain performance. Understanding these principles will aid in achieving a force greater than 0.001N without circuit overheating.

Small Simple Electromagnet...Help Please!

hi
I'm trying to make a simple small electromagnet using a core from electric drill transformer (I think its called permalloy if I'm not mistaken) which i machined into 17mm long and 2mm diameter. How can i make it powerful enough to produce a force of more than 0.001N without overheating the circuit. I'm using a 0.125mm insulated copper wire, powered by a Manson EP-613 power supply (0-30V , 2.5A DC power supply)

Can anybody point me to a right direction? Such as formula needed for the calculation of voltage and current needed and advice on the design itself would be appreciated.

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
