## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA3873:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA3873:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

Ever wanted to [feel like Magneto](https://www.youtube.com/watch?v=2VmqIwB11yE)? Well, now you sort-of can! Bring the ferromagnetic objects in the world under your control with an **Electromagnet**

The simplest way to make an electromagnet is to get a solenoid, pass some current through it, and then get a piece of soft iron inside the solenoid. When the current is switched off, the electromagnet is no longer, well, magnetic!

What this means is that you just need to power this here electromagnet with about **5VDC** (you don't have to be exact, 4-6V will work fine) and ka-pow, it's now a magnet. Turn off the power and it reverts back to a normal chunk of metal. Since its a coil, you'll need to use a motor or solenoid driver with kick-back protection. Adafruit's Crickit boards will work great.

**Please note: electromagnets are specified with "holding force", say 5 Kg / 11 lb**. *This is not how much weight they can pick up!* **Divide the holding force by 5-10 to get a rough estimate of how heavy a thing it can pick up**. So in this case, about 1 Kg / 2 lb max. Note that pick-up weight also depends on a flat surface and max surface contact, and the ferromagnetic metal content. A perfectly flat steel cube will work great, something oddly shaped or covered in rubber or plastic will not!
