This following applet is twolinesBfield
Created by prof Hwang Modified by Ahmed
Original project twolinesBfield

There is current flow I in the z direction (along z-axis) which will produce circular magnet field.

There is another current i along x direction initially (i<<I), the direction of thos current can be adjusted with slider.

The magnet force between current segment, $i d\vec{\ell}$ in magnetic field $\vec{B}=\frac{\mu_o I}{2\pi r}\hat{\theta}$ is $d\vec{F}=i d \vec{\ell}\times \vec{B}$

The direction of current is represented with red arrow. Gray arrows are magnetic field, Blue arrows are interaction force.

• Please feel free to post your ideas about how to use the simulation for better teaching and learning.
• Post questions to be asked to help students to think, to explore.
• Upload worksheets as attached files to share with more users.
Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!
