Magnetic Field Strength Meter

Multi field emf meter measures magnetic field electric field and radio frequency strength.

Magnetic field strength meter.

All are calibrated at 72 f. Magnetic field lines form in concentric circles around a cylindrical current carrying conductor such as a length of wire. In addition to measuring the strength of a magnetic field in gauss they also measure the direction of a magnetic field in positive negative. The device may also be referred to as an electromagnetic field detector or emf detector for short.

T is a derived unit of the magnetic induction also magnetic flux density in the international system of units. The direction of such a magnetic field can be determined by using the right hand grip rule see figure at right. To take a measurement place the lower edge of the indicator near or against your tools and parts. These indicators come with a calibration certificate traceable to nist that states they ve passed a test for accuracy.

Magnetisation defines the material s response it is magnetic moment per unit volume of material. One tesla is equal to one weber per square metre the unit was announced during the general conference on weights and measures in 1960 and is named in honour of nikola tesla upon the proposal of the slovenian electrical engineer france avčin. You ll be able to measure electric magnetic radio or microwave field strength for anything from cell phones to nearby power lines. Quantity called magnetic field strength magnetizing force is a measure of the applied magnetic field from external currents independent of the material s response.

The strength of the magnetic field decreases with distance from the wire. 4 6 out of 5 stars 762. Emf elf meter high sensitivity emf elf meter with built in single axis sensor. Cgs unit of magnetic field strength is oersted and si unit is ampere meter.

Gaussmeter s are simple to use and handheld versions are available which can be carried to monitor magnetic fields as you walk. Electric field radio frequency rf field magnetic field strength meter by trifield emf meter model tf2 detect 3 types of electromagnetic radiation with 1 device made in usa by alphalab inc. Magnetic fields are emitted by electrical circuits in domestic and office environments whilst high frequency radio radiation can be emitted by tv transmission installations and radio transmitters. A gaussmeter also known as a magnetometer is a device used to measure the strength and direction of a magnetic field.

The cornet meter measures electric magnetic and radio emissions simultaneously so it s not always possible to isolate the specific type of field being generated. Get it as soon as wed sep 30.
