What Sensor?(AC240V 60Hz) Magnetic Flux Density Measurement (Tesla) with Arduino

** What sensor should I use for the measurement of Magnetic flux density that come from power cables? (AC Power cables, typically 240 Volts and 10 Amp or lower >> 60Hz). **

I am currently conducting a study regarding the induced EMF by AC power cables on a copper plate. These power cables are your typical cables that carry electricity to your appliances and devices. Also, I am new to Arduino and I want to use it to measure the magnetic field produced by such cables.
