Using AC to Pulse a Relay Module

I'm trying to use a simple coil winding to trigger a relay module.  It's got me stumped.

The circuit in the upper left corner triggers the relay with a simple grounded DC voltage.

I'm trying to get the circuit directly below that to trigger the relay using an AC source but I just can't figure out how to set it up.  (NOTE: It's an air core coil, so no ground point, just a magnet passing over it to stimulate it.)

Here's the relay module I'm trying to trigger: https://www.aliexpress.com/item/1005001903120199.html

Any thoughts on how I should be connecting these two items?  FYI: I don't have a clue what I'm doing. lol

Thanks, Vince.

Never mind, I thought the '8 Channel Relay Module' was the same as an '8 Channel Solid State Relay (SSR)'. I understand now that they are not. The '8 Channel Relay Module' can only be used with an input signal from something like an Arduino or a 'Reflective Photoelectric 3pin IR Infrared Sensor Module'. The '8 Channel Relay Module' also operates much slower than I want so I'll go back to working with good old fashion SSRs with 4 terminals.
