Action: Show components and field module in real time. Application: Educational Teslameter, graphs, research of household sources. Limitations: These are phone sensor readings; Accuracy depends on model and calibration. Equipment: Phone without external magnet. Preparation: Easy start. Type: Application script. <a id=\"variant-m089\"></a>\n- Comparison of magnetic objects. Action: In the same position, compare the relative readings from the samples. Application: Physics lesson, sorting prepared samples, studying magnets. Limitations: Not a universal metal detector: copper, aluminum and any hidden objects are not detected reliably. Equipment: Magnetic props with a given geometry. Preparation: Needs setup. Type: Application script. <a id=\"variant-m090\"></a>\n- Study of poles and field lines. Action: Invert a known magnet and measure the field at marked points. Application: School experiment, interactive explanation of vector and superposition. Limitations: Interpret polarity only taking into account the geometry and coordinate system. Equipment: Magnetic props with a given geometry. Preparation: Needs setup. Type: Application script. <a id=\"variant-m091\"></a>\n- Coil as a signal source. Action: External controlled coil creates slow field changes for recognition. Application: Current training experience, prepared beacon, low speed command. Limitations: Requires external electronics, tested field levels and frequencies; This is not NFC or a radio modem. Equipment: External active electronics. Preparation: Experimental. Type: Application script. <a id=\"variant-m092\"></a>\n- Counting machine cycles. Action: A magnet attached to a slowly rotating mechanism produces a periodic signal. Applications: Toy tachometer, revolution counter, frequency study. Limitations: Sampling rate and filters limit speed; Missing pulses and aliasing need to be checked. Equipment: Magnetic props with a given geometry. Preparation: Experimental. Type: Application script. <a id=\"variant-m093\"></a>\n- Scoring and field drawing. Action: Convert a signal into sound, color, shape or movement. Applications: Music installation, generative art, sensory learning. Limitations: This is an artistic display; sound strength or brightness is not the physical energy of the field. Equipment: Telephone and external magnet. Preparation: Easy start. Type: Application script. <a id=\"variant-m094\"></a>\n- Alternative physical input. Action: Set up a convenient magnetic switch or regulator in a stable mount. Application: Input with difficult touch, large button, operation with gloves. Limitations: Design and force are selected with the user; a backup control method is needed. Equipment: Magnetic props with a given geometry. Preparation: Needs setup. Type: Application script. <a id=\"variant-m095\"></a>\n- Accessory profile. Action: Recognize the prepared accessory when attached and change the application mode. Application: Working panel, camera mode, game profile, interactive stand. Limitations: Support depends on geometry and OS; the launch of system actions is not guaranteed, MagSafe is not equal to the identification API. Equipment: Magnetic props with a given geometry. Preparation: Experimental. Type: Application script. <a id=\"variant-m096\"></a>"},{"id":"context","title":"Context and limits","body":"Author's working classification for designing games and interactions.
