How i can write an equation in SIMSCAPE script which is dependent on the output of that component?

For example, I want to make a mutual inductor where mutual inductance M is a function of output current i1. How i can write that. Can anybody help me regarding this?

I would be really grateful for it.

Thanks Shahriar ============================================================================= For your referrence : The code is written below =============================================================================

component mutual_inductor_paper

nodes
  p1 = foundation.electrical.electrical; % +:left
  n1 = foundation.electrical.electrical; % -:left
  p2 = foundation.electrical.electrical; % +:right
  n2 = foundation.electrical.electrical; % -:right
end

parameters
  L1 = { 1, 'H' };  % Toroidal inductance
  L2 = { 2, 'H' };  % Poloidal inductance
  pip = { 1, 'W' };  
  tim = { 1, 's' };  
  i10 = { 0, 'A' };  % Winding 1 initial current
  i20 = { 0, 'A' };  % Winding 2 initial current
end

variables
  i1 = { 0, 'A' };
  v1 = { 0, 'V' };
  i2 = { 0, 'A' };
  v2 = { 0, 'V' };
end

function setup
  through( i1, p1.i, n1.i );
  across( v1, p1.v, n1.v );
  through( i2, p2.i, n2.i );
  across( v2, p2.v, n2.v );

    i1 = i10; % Initialize current for winding 1
    i2 = i20; % Initialize current for winding 2
  end

equations
    let

          M = pip*time/(i1*^2)
      in

    v1 == L1*i1.der + M*i2.der;
    v2 == L2*i2.der + M*i1.der;
  end
  end
end

Is it possible to write the equation you want to implement? Does this code work for you currently (minus the feature you are asking about)?
