EMI - current direction in loop

In summary, EMI stands for electromagnetic interference and can cause malfunctions, disruptions, or even total failure of electronic devices. The current direction in a loop refers to the flow of electrical current in a closed circuit and can affect EMI by creating electromagnetic fields or acting as an antenna. EMI can be reduced through proper shielding, grounding, and circuit design.

The Attempt at a Solution



I think that both i1 and i2 will have same mag and direction
and at same time the loop is not closed so will there be any current?

the loop is closed …

it's not a bent solid bar, it's only the outline of one :wink:​

Oh YES ! :eek:

That solves the problem!
Thanks a lot tiny-tim :biggrin:
 

Related to EMI - current direction in loop

1. What is EMI?

EMI stands for electromagnetic interference and refers to the disturbance of electronic devices caused by electromagnetic radiation or induction from other nearby electronic devices.

2. How does EMI affect electronic devices?

EMI can cause malfunctions, disruptions, or even total failure of electronic devices. This interference can lead to errors, reduced performance, or permanent damage to the device.

3. What is the current direction in a loop?

The current direction in a loop refers to the flow of electrical current in a closed circuit. In a loop, the current flows from the positive terminal of a power source to the negative terminal and back again, creating a continuous loop.

4. How does the current direction in a loop affect EMI?

The current direction in a loop can affect EMI in two ways. First, if the loop is not properly shielded, the current flow can create electromagnetic fields that can interfere with nearby electronic devices. Second, if the loop is not properly designed, it can act as an antenna, picking up external electromagnetic radiation and causing interference in the circuit.

5. How can EMI be reduced in electronic devices?

EMI can be reduced in electronic devices through proper shielding, grounding, and circuit design. Shielding can prevent external electromagnetic radiation from entering the device, grounding can dissipate excess electrical energy, and proper circuit design can minimize the effects of EMI on the device's performance.
