Discussion Overview

The discussion focuses on creating an electromagnetic device, specifically a DC electromagnet, and involves inquiries about the necessary formulas for calculating voltage, current, wire resistance, and the relationship between magnetic force and mass. The scope includes theoretical and practical aspects of electromagnet design.

Discussion Character

  • Technical explanation
  • Mathematical reasoning
  • Homework-related

Main Points Raised

  • One participant seeks guidance on how to create an electromagnet and requests formulas for calculating voltage, current, number of wire turns, and wire material.
  • Another participant suggests measuring the wire's resistance and provides the formula V = IR to relate voltage, current, and resistance.
  • A participant expresses familiarity with Ohm's law but requests specific equations for designing a DC electromagnet.
  • A link is provided by a participant, which claims to contain relevant information about solenoids and their properties.
  • A further inquiry is made regarding the relationship between magnetic field strength (B) and force (F) in the context of moving a 2 kg mass using magnetic force.

Areas of Agreement / Disagreement

Participants appear to have differing levels of understanding and focus on various aspects of electromagnet design, with no consensus on the specific equations needed for the design or the relationship between magnetic field and force.

Contextual Notes

Participants have not fully defined the assumptions regarding wire material, dimensions, or the specific configuration of the electromagnet, which may affect the calculations and relationships discussed.

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
