The Turam method is a geophysical survey technique used primarily for mineral exploration. It's an electromagnetic method which uses large loop sources to induce currents in the earth. Here's a step-by-step explanation of the principle behind the Turam method:

1. **Transmitter Loop**: In the Turam method, a large loop of wire, often several hundred meters to a kilometer on a side, is laid out on the ground. This is the transmitter loop. An alternating current is passed through this loop, which creates a primary magnetic field that penetrates into the ground.

2. **Induced Currents**: This primary magnetic field induces eddy currents in the subsurface. These eddy currents are strongest in conductive materials, such as metallic ore bodies.

3. **Secondary Magnetic Field**: The eddy currents generate their own magnetic field, known as the secondary magnetic field. This secondary field is superimposed on the primary field and can be detected and measured at the surface.

4. **Receiver Coil**: A receiver coil is moved along a line that crosses the transmitter loop. The receiver measures the total magnetic field, which is the sum of the primary and secondary fields.

5. **Anomalies Detection**: By comparing the measured total field with the expected primary field, anomalies can be detected. These anomalies may indicate the presence of a conductive ore body.

6. **Data Interpretation**: The data collected is then interpreted to provide information about the location and size of any conductive bodies in the subsurface.

The Turam method is a powerful tool in mineral exploration, particularly for deep or buried ore bodies. It's a non-invasive and cost-effective way to explore large areas of the subsurface.
