SUMMARY

This discussion focuses on creating an electromagnetic device using wire winding techniques. Key formulas provided include Ohm's Law (V = IR) for calculating voltage, current, and resistance, which are essential for designing the electromagnet. The user seeks to understand the relationship between magnetic field strength (B) and force (F) to move a 2 kg object using magnetic force. Resources such as the HyperPhysics solenoid page are recommended for further calculations and design considerations.

PREREQUISITES
  • Understanding of Ohm's Law (V = IR)
  • Familiarity with electromagnetic principles and solenoid design
  • Knowledge of measuring resistance using an ohm-meter
  • Basic concepts of magnetic fields and forces
NEXT STEPS
  • Research solenoid design principles on HyperPhysics
  • Learn about calculating magnetic field strength (B) in solenoids
  • Explore the relationship between magnetic force and mass for moving objects
  • Investigate materials suitable for wire in electromagnet construction
USEFUL FOR

Electronics enthusiasts, physics students, and engineers interested in electromagnet design and applications in moving objects using magnetic forces.

Hello
i want to create an electromagnetic with rounding the wire such as ithttp://education.jlab.org/qa/em_02.jpg"

could you tell me how can i do it with formula?(because i want to calculate voltage , amper, Number of rounding and the material of wire)

you need to know the resistance of the wire either on a per-unit-length basis or simply measure the resistance of how much wire you are using. You need an ohm-meter for this.

the relationship between voltage, amperes and resistance is this:

V = IR

V=voltage in volts
I= current in amperes
R = resistance in ohms

If you are planning on using a 1.5V battery, then I = 1.5/R, for example.
 
Thanks gsal
i know the ohm equation
i want to design a DC electronic magnate such as picture that you see.i need equation of calculation of my purpose.
 
Thanks
could you tell me the relationship between B(magnetic filed) and F(Netwon)? i want to move an 2kg with magnetic force
