Can a Magnetic Field Lift Steel Balls in a Coiled Wire Setup?

Click For Summary
SUMMARY

The discussion centers on the feasibility of using a magnetic field generated by coiled enamel-coated magnet wire to lift hollow carbon steel balls, each weighing 127.005g. The setup involves a 12-volt current passing through the wire, creating a magnetic field around a plastic tube with an inner diameter of 1.625 inches. Participants are tasked with determining whether the magnetic field strength is sufficient to lift the steel balls and calculating the maximum weight that can be lifted. Key equations related to magnetic force and field strength are essential for this analysis.

PREREQUISITES
  • Understanding of electromagnetism principles
  • Knowledge of magnetic field strength calculations
  • Familiarity with the Lorentz force equation

Homework Statement



Hello,
I am working on a project in which hollow carbon steel metal balls(1.5" diameter)(weighing 127.005g a piece) are placed in a plastic tube (1&5/8" innner diameter). Surrounding the plastic tube is enamel coated magnet wire(coiled around the plastic tube) in which a current(12 volts) is passing through the wire thus creating a magnetic field. My question is will the magnetic field be strong enough to lift the balls. Also what is the maximum weight that magnetic field produced can lift? Please include equations used. If you need any more details please feel free to ask. Thank You
