Trying to make an electromagnetic shaker device

AI Thread Summary
Creating an electromagnetic shaker device by wrapping an iron core with a solenoid and using AC to shake a magnet is feasible but may not be the most effective approach. A variable speed DC motor with an eccentric weight is suggested as a more practical solution for achieving controllable shaking at various power levels. The discussion emphasizes the importance of defining specific requirements such as the weight to be shaken, desired speed, and distance for effective design. While solenoids can be used, they may not offer the convenience needed for certain applications. Overall, the feasibility of the electromagnetic shaker depends on the specific parameters of the intended use.

Hello, I'm trying to make an electromagnetic shaker but I'm not sure if this is possible? Basically I want to wrap an iron core with a solenoid and use AC to shake a magnet at some distance away. I'm not certain on the approach at the moment but I'm kind of looking at the feasibility at the moment.

If you want to shake something at a variable and controllable rate then a variable speed DC motor with an eccentric weight on the shaft will satisfy many requirements. Crude but very effective and will work at a range of powers. 500W Brushless motors are available for small machine tools and they work well. The motor can be fixed rigidly and the eccentric can be at the end of a flexible shaft if you need high power.
Driving a solenoid with a variable low frequency power signal is nothing like as convenient.
What is the precise requirement?
 
Feasibility depends on the power and the distance.

What are you trying to shake?
How fast?
What distance?

As @Bystander said, a speaker is a shaker. But if you want to shake a ton of gravel that's very different.

Thread 'Maxwell stress tensor'

This is from Griffiths' Electrodynamics, 3rd edition, page 352. I am trying to calculate the divergence of the Maxwell stress tensor. The tensor is given as ##T_{ij} =\epsilon_0 (E_iE_j-\frac 1 2 \delta_{ij} E^2)+\frac 1 {\mu_0}(B_iB_j-\frac 1 2 \delta_{ij} B^2)##. To make things easier, I just want to focus on the part with the electrical field, i.e. I want to find the divergence of ##E_{ij}=E_iE_j-\frac 1 2 \delta_{ij}E^2##. In matrix form, this tensor should look like this...

Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'

Please can anyone either:- (1) point me to a derivation of the perpendicular force (Fy) between two very long parallel wires carrying steady currents utilising the formula of Gauss for the force F along the line r between 2 charges? Or alternatively (2) point out where I have gone wrong in my method? I am having problems with calculating the direction and magnitude of the force as expected from modern (Biot-Savart-Maxwell-Lorentz) formula. Here is my method and results so far:- This...
