I tried with a small motor magnet and was able to produce "123" and "Hi" that were legible from the front.Not sure if that is useful for you. **Q: Will this show the tracks on magnetic audio tape?** A: Not usefully. It might just show some magnetic field on a cleverly recorded tape (eg: Like a lightning flash recorder), but neither the resolution nor the contrast would show normal audio tracks. That is simply not it's function. ## Frequently Bought Together - Magnet Source Magnetic Field Viewer Card (Pack of 1) - The Original Slinky Walking Spring Toy, 2.75-inch Diameter Metal Slinky, Fidget Toys - The Hillman Group 123113 18 Aluminum Display Package, 50-Feet, 1-Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/292708072-master-magnetics-magnet-source-field-viewer-card-pack-of-1](https://www.desertcart.pt/products/292708072-master-magnetics-magnet-source-field-viewer-card-pack-of-1) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-14*
